A Scalable K-Band 256-Element Receive Dual-Circularly-Polarized Planar Phased Array for SATCOM Application

This paper has presented the design of a low profile K-band 256-Element receive dual-circularly-polarized planar phased array, which consists of $16 \times 16$ radiating antenna elements, 64 beamformer chips, a beam-forming network and a beam control unit. This antenna system has the advantages of low profile, light weight, high integration and flexible extensibility. It is a promising solution for LEO satcom application.
