The influence of reflections on radiation patterns

The dipole is the oldest and most approved radia-

ting element in the field of mobile communication.

It is the basis for nearly every professional anten-

na type such as the yagi antenna, the log. peri-

odic antenna, and particular the panel antenna.

The latest development of panel antennas leads

to the sophisticated technology of slanted dual

polarization (Xpol).

Is the dipole technology suitable to fulfil the

growing and stringent requirements ? Can

these odd metal structures still compete with

newer solutions like the patch radiator on a

printed board ?

The answer is definitely yes ! This article will

show that the dipole technology more than other

concepts provide the flexibility to perfect certain

characteristics without the effect of destroying

others. This feature is specific important for the

design of dual band cross-polarized antennas.

2.1 General description

Electrical :

Xpol antennas consist of two independently wor-

king slanted dipole systems, one for

+45° polarization and the other for -45° polariza-

tion.

The dipoles are symmetrically positioned in front

of a reflector screen. Both the power distribution

and the impedance transformation are carried out

by a low loss cable harness. Additional elements

for beam-shaping and isolation perfect the

design.

Mechanical:

The radome consists of a completely closed self-

supporting fiber-glass profile, into which the metal

parts are inserted. There are no drill-holes at all in

the profile, which is closed by two end caps with

short sealing rings. This concept offers ideal

permanent protection against environmental

influences and increases the

mechanical stability.

The improved separation of the electrical and the

mechanical function facilitates the optimization of

particular performances.

2.2. Outstanding characteristics

2.2.1 Symmetrical construction

Xpol antennas are available with horizontal half

power beam widths of 65° and 90°. Starting from

a standard vertical polarized antenna, the requi-

red dipole-pair for 65° and the single dipole for

90° are rotated by +45° and -45°, resulting in

orthogonal polarizations (see fig. 1).

While the dipoles of the 90° type form an „X“ on

which the expression Xpol antenna is based, the

basic 65° dipole system is a rhomb.

Both designs are fully symmetrical referred to

the center line of the reflector screen, which is

the basic condition for symmetrical horizontal

radiation patterns .

2.2.2 Beam-shaping

The dipole technology offers a high flexibility in

modeling the radiation patterns.

Beam width and shape are defined by the dipole

position to the reflector and the reflector dimen-

sions. Particular the vertical edges of the reflector

screen have a decisive influence on vertically

polarized components.

For slanted polarizations, consisting of vertical

and horizontal components, parasitic elements in

the reflector screen as further beam-shaping ele-

ments are added, which mainly have an effect on

horizontally polarized components.

Thus already the patterns of the basic dipole

system are optimized, which means a great

benefit in combining them. The quality of the

resulting pattern is improved regarding sidelobes

and gain, and the required number of single ele-

ments is minimized (see item 2.2.4.).

In addition, with the separate adjustability of the

vertical and the horizontal components, the resul-

ting polarizations are controllable.

Orthogonal polarizations provide the best pola-

rization diversity gain results, therefore the hori-

zontal radiation patterns for the vertical and the

horizontal component are standard measure-

ments for Xpol antennas.

If the patterns half power beam widths and there-

by the gain values resp. the amplitudes are iden-

tical, the polarizations are orientated +/- 45° and

consequently orthogonal (fig. 2).

Fig. 2: Vertical (V) and horizontal (H) components and resulting polarizations:

a) Equal amplitudes (V=1/H=1) → orthogonal polarizations

b) Different amplitudes (V=1/H=0.7) → non-orthogonal polarizations

The polarization diversity technology assigns

both systems of an Xpol-antenna to work in the

Rx- and Tx-mode simultaneously. Therefore a

minimum isolation of 30 dB between the antenna

inputs is required.

Kathrein’s dipole design guarantees a min. isola-

tion of 32 dB. Measurements of each antenna

during the production show a typical value of 35

dB !

Within the basic dipole system („X“ and „rhomb“),

the symmetrical construction provides high isola-

tion, while the isolation from one bay to the next

is improved by patented decoupling measures.

A perfect polarization orthogonality results in a

high cross-polar ratio (CPR), which is determined

by measuring the horizontal radiation patterns

with the operating polarizations +45° and -45°.

The CPR compares the level difference between

the similar polarized signals (co-polar) and the

dissimilar polarized signals (cross-polar) of the

radiated wave. A high CPR stands for a high

uncorrelation of the two signals and consequent-

ly for a good polarization diversity performance.

The dipole design provides excellent values also

apart from the main direction (coverage sector

width +/- 60°) and even at +/- 90° (see item 4)!


2.2.3 High isolation between the two antenna systems

Low-loss flexible semi-rigid coax cables distribu-

te the power to each dipole and take care of the

impedance transformation. The diameter of the

cables (and the corresponding attenuation)

varies with the application, diameters of 0.250″,0.141″ and 0.085″ are in operation.

This system produces only a minimal attenuation,

which will become apparent by comparing it with

a printed circuit solution. As a standard the corre-

sponding cross-section of the conductive lines is

between the 0.085″ and the 0.141″ cable.

In addition these lines are open and radiate a part

of the power, which causes further losses.

That means, to reach the same gain values,

antennas using a printed board power distribution

have to compensate the higher losses by additio-

nal bays of radiating elements! This results in a

roughly 20% higher vertical antenna length and a

smaller vertical beam width.

Another advantage of the cable harness is the

flexibility regarding versions with electrical down-

tilt. The required variation of the phase relations

between the radiating elements is carried out

easily by changing the length of the cables. It is

not necessary to redesign the entire antenna.

2.2.4 Low-loss power distribution by cables

6


Since more than 15 years Kathrein is doing rese-

arch on the reduction of intermodulation (IM) pro-

ducts. There was already a self-designed measu-

ring device for IM products at 450 MHz with a

dynamic range of 160 dB in operation, when such

a device was not available on the market.

The extremely valuable experiences flowed into

the antenna design and determine for example

the applied material, the possible material combi-

nations and how a contact between two parts

should look like.

Kathrein antennas provide a typical 3rd order

IM-products attenuation of -150 dBc using two

transmitters with an output power of 20 W

(43 dBm) each.

2.2.5 Low intermodulation products

Antennas are confronted with all the environ-

mental influences such as cold and hot tempera-

tures, rain, ice, snow, lightning and high wind

velocities.

Kathrein antennas are well prepared, the mecha-

nical design is based on the environmental con-

ditions according to ETS 300 019-1-4.

Regarding the deviation of the electrical parame-

ters, especially rain, ice and snow on the radome

may cause problem because of their dielectric

parameters. Due to the fact that the antenna dep-

ths became smaller and smaller, this dielectric

load is very close to the radiating elements, wor-

king as an additional capacity. Consequently the

operational frequency range is shifted, which

goes together with the deterioration of electrical

parameters like VSWR, isolation and CPR.

The Kathrein dipole technology is highly resistant

against rain, ice and snow. Dipoles are very slim

structures with a small surface and therefore the

occurring additional capacity is relatively low.

Due to their larger surface, the capacity in-

fluence on patches is much higher. For example,

a wet radome can change the isolation of a patch

antenna significantly, while a dipole antenna

reacts much more good natured.

2.2.6 Continuance of the electrical parameters against enviromental influences

7


The following antenna parameters have a decisive

influence on the network and are important for the

judgement of antennas :

1. Half power beam width for co-polar polarization

2. Half power beam width for vertical / horizontal polarization

3. Front-to-back ratio - co-polar

4. Front-to-back ratio - total power

5. Cross-polar ratio

For a high cross-polar attenuation the half power

beam widths of the three polarization components

co-polar, vertical and horizontal are similar. This fea-

ture is perfectly performed by Kathrein´s Xpol-

antennas and consequently there is no need for net-

work planning reasons to differentiate between the

above polarization components.

These measurements also provide the front-to-back

ratio, which is an important feature for the network

planning. The front-to-back ratio can be determi-

ned as the worst case of either the vertical or the

horizontal polarized components. It is only requi-

red to calculate the total power, if the two compo-

nents have similar levels. In case of identical

levels, the total power value is 3 dB less compa-

red to the individual components.

Xpol dipole antennas provide typical front-to-back

ratios of 24 – 30 dB total power.

The following figures show the co-polar and

cross-polar as well as the vertical and horizontal

polarized patterns of 65° and 90° antennas.

Beside the symmetry of the patterns, the scalar

printout with a linear scale in dB shows clearly the

cross-polar ratio in each azimuth direction. The

dipole design provides excellent values also

apart from the main direction and even at +/- 90°!

Please note as well the high front-to-back ratio for

the co-polar and the cross-polar signal.

As already mentioned, the dipole design provides

excellent CPR values not only in main direction

but even at +/- 90°.

It is important for the coverage of a standard sec-

tor, to rely on high CPR values and consequently

on high diversity gains also at the sector edges,

where the antenna gain is already considerably

reduced.

Dual-Band Combiner800 – 1000 / 1700 – 2000 MHz

The dual-band combiner can be used:– to combine several transmitting and receiving frequencies in two frequency bands to a common feeder cable, to a broad-band antenna or to

a broad-band radiating cable at port 3,– and, in reverse operating mode, to separate several transmitting or receiving frequencies into two frequency bands (base stations) at port 1

and port 2.

Design and construction:The dual-band combiner consists of a low-pass filter (band 1) and a high-pass filter (band 2) in printed circuit technology. Both bands provide a DC by-pass function to enable mast head amplifiers to be supplied with DC voltage.The dual-band combiner is designed for use either as an indoor or outdoor device.

TETRA / TETRAPOL Technology

The worldwide market for professional mobile com-

munication is estimated DEM 10.000 millions per

year. Around one third of this amount is for Europe.

A new digital standard shall replace the analog

systems.

This new standard is the basis for a paneuropean

Network.

The frequency bands for this purpose were fixed at:

1. 380 – 400 MHz for systems for police,

life-saving organisation, fire brigades, ...

2. 410 – 430 MHz for public purpose in the

industry

Two digital standards are in competition for the pre-

dominance in this big market. TETRA (TErrestrial

Trunked RAdio) and TETRAPOL. TETRA is stan-

dardised by ETSI (European Telecommunication

Standard Institute) whereas TETRAPOL has the

bigger practical experience. About 30 TETRA-

POL-networks in 15 countries are working. But

since about one year, in several european coun-

tries also a TETRA-Network with international

roaming is just being build up.

The advantages of TETRA compared to GSM

are:

1. The possibilitiy to send statusmessages

2. Short data transfertimes (typical 100 msec)

3. Groupcalls

4. Individual signalling and access authorisation

for subscribers

5. Direct mode

6. High frequency economy

... and a few more.

Kathrein offers omnidirectional antennas as well as

panel antennas for vertical polarization (half-power

beam widths 65°, 90° and 115°) and cross polariza-

tion (half-power beam width 65°) with lengths from

1 m up to 2.6 m.

Of course all antennas are constructed in the well

approved Kathrein standard technology.

1. Lots of reflections from the walls, ceiling,

floor, furniture and persons (see sketch

above), destroy the free space radiation

patterns and the corresponding antenna gain.

2. The dimensions of normal rooms do not fulfil

the far field conditions (distance to the

antennas more than 3 m for GSM 900,

respectively 1.5 m for GSM 1800).

3. Therefore the measured far field patterns do

not apply; specific radiation patterns and

gains provide no benefit within closed rooms.

Kathrein refers to this physical facts with its pre-

sent indoor program with mainly two omni versi-

ons for ceiling mounting and one directional

antenna for wall mounting.

Apart from single band antennas, also multiband

versions are available.

Indoor Environment

Typical room

Indoor antennas just convert the RF power

Most clients prefer unobtrusive antenna appea-

rance in indoor applications. Kathrein reacted on

this demand by redesigning the most sold indoor

antennas 737 602 and 738 749.

The shape of the new models 741 571 and

741 572 adapts perfectly to the requirements of

modern buildings. In addition these antennas are

multiband types operating from 824 – 2170 MHz

and suitable for UMTS as well.

Unobtrusive design

Especially for the signal distribution within bigger

buildings with lots of indoor antennas, it is neces-

sary to design an indoor network with more or

less similar signal levels in all floors. Therefore

Kathrein provides 2-, 3- and 4-way splitters and

splitters with unequal power splitting (“Tappers“).

The resulting distribution attenuation (valid for

both directions), are given with the following

survey:

The impact of increasing data over the fixed net-

work and the explosion of mobile usage has

shown the trend for future high data mobile com-

munication. Therefore UMTS (Universal Mobile

Telecommunications System) is the realisation of

a new generation of mobile communications

technology for a new world of combined fixed and

wireless mobile services and a broad offer of

communication services (see picture above).

Due to this fact, the requirements for UMTS are:

1. Provision of unified presentation of services to the user in wireless and wired environment.

2. Mobile technology that supports a very broad

mix of communication services and applications.

3. On-demand flexible bandwidth allocation and in a wide variety of applications.

4. A standardisation that allows full roamingwhere needed, but also responsive to pro-prietary, innovative and niche markets.

Meanwhile all big system suppliers make exten-

sive trials on UMTS systems. Despite some

ongoing conflicts about existing patents for the

new standard, most commentators expect a start

of the new system as planned. In spring of the

year 2001, the japanese network operator NTT

Docomo intends to launch the first UMTS-Net.

Third-Generation Mobile Communications – UMTS

Kathrein has early reacted on the new demand.

We already offer three antennas with vertical

polarisation for the established frequency band of

1920 – 2170 MHz, for tests and evaluation pur-

pose. Of course also dual polarized and multi

band antennas are already in development.

Though it is a totally new frequency band, all

antennas appear in the well approved quality,

known from the GSM 900 and GSM 1800

Kathrein antenna program.
