Amplifier-Integrated Active Array Antennas for millimeter-Wave Radar

Abstract

Modern wireless systems, especially at millimeterwave, place increasingly stringent requirements on size, weight,
power and cost (SWaP-C). In this talk we present an overview of our recent work on active beamsteering array antennas for mmwave sensing applications, highlighting an active transmitarray antenna for Ka-band (34-36 GHz) monopulse tracking radar with commercial SiGe-based beamforming chips developed for 5G. Moreover, an outlook is given towards higher levels of integration between electronics and array antennas, where codesign techniques such as direct matching and in-antenna combining may help optimizing output power and efficiency.
