Abstract

This paper describes the design and demonstration of a 1024 element coded aperture subreflector array, implemented with single-bit phase shifters that utilize GaN HEMTs to modulate signals upon reflection. An active reflect-array enables digital beamforming using a single 235 GHz radar transceiver. Wafer level fabrication and assembly allows large arrays to be tiled up while maintaining reasonable costs.
