‡{seki.tomohiro, kawashima.munenari}@lab.ntt.co.jp Abstract Microwave Power Transmission (MPT) in high frequency is essential to broaden a range of MPT applications. Our
research group has developed discrete 24GHz-band rectifier. In this paper, we developed small-sized MMIC 24GHz-band rectifier. We adopted class-F load as an output filter, and the area of the MMIC rectifier was 2.3mm2. We obtained the RF-dc conversion efficiency of 48.0% when the input power was 194mW and the resistive load was 140 . We fabricated patch antenna with the Teflon substrate and developed an MMIC-mounted rectenna. We conducted a 24GHz MPT experiment with a 2×2 MMIC-mounted rectenna array, and succeeded motor drive by 24GHz MPT.
