Millimeter-Wave Transmitter and Receiver with Efficient IC-Antenna Interface for Sensors, Phased-arrays and Polarization-Duplexing

Millimeter-wave(mm-wave) is a key technology for 5G and IoT. Shrinking antenna size and limited power amplifier output power suggests phased array is necessary in order to satisfy the link budget at mm-wave. However, the IC-antenna interface is challenging at mm-wave and could limit the overall system efficiency. To solve this problem, an efficient IC-antenna co-integration approach is proposed to achieve good overall efficiency, large bandwidth and is also wafer scale compatible for mm-wave sensors and phased arrays. Then this approach is extended to achieve concurrent dual-polarization receiving for short-range imaging/comm applications and polarization-diversity based MIMO links. Lastly, a simultaneous transmit and receive TRX front-end with co-integrated antennas to achieve efficient polarization-duplexing is presented. It is attractive for mm-wave phased arrays, low-latency links and relays.
