A 4×1 L-band conformal receiving array with full digital beamforming for four simultaneous polarizations and sidelobe suppression is presented. The array is based on a reconfigurable quad-polarization antenna featuring four primary patches with secondary patches to enhance the bandwidth. The resultant 16 channels are combined into eight channels through hybrid couplers which introduce the required fixed phasing. The eight channels are digitized and processed in an AMD radio frequency system-on-chip (RFSoC). The polarizer for the four polarizations (HP, VP, LHCP, and RHCP) and the beamformer are implemented in the RFSoC as well as suppression of sidelobe levels (SLL). The beamforming performance of the conformal array is demonstrated for several beamsteering cases.
