A 4×1 L-band receiving phased array with full digital beamforming for four simultaneous polarizations is presented. The array is based on a reconfigurable quad-polarization antenna consisting of four patches with secondary patches to increase the bandwidth. The resulting 16 channels are combined into eight channels using hybrid couplers that provide a layer of fixed phasing. The eight channels are digitized using a Xilinx radio frequency system-on-chip (RFSoC) and the polarizer for the four polarizations (V, H, LHCP, and RHCP) and the beamformer are implemented in the RFSoC. The beamforming performance for the four simultaneous polarizations is demonstrated.
