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

Antennen . Electronic
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
Antennen . Electronic
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.

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.

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.
