Multi-beam phased array for first and second polarized satellite signals

Abstract

Systems and methods disclose a satellite communication system including a plurality of antenna elements, an interface circuit, and a transceiver circuit. Each antenna element communicates a first polarization signal and a second polarization signal. The interface circuit receives, amplifies, and splits the first polarization signals into a first polarization primary signal and a first polarization secondary signal. The interface circuit also receives, amplifies, and splits the second polarization signals into a second polarization primary signal and a second polarization secondary signal. A first summer circuit generates a first beam signal via a sum of the first and second polarization primary signals. A second summer circuit generates a second beam signal via a sum of the first and second polarization secondary signals. The transceiver includes a first splitter circuit that receives and splits the first beam signal into a first signal and a second signal, a second splitter circuit that receives and splits the second beam signal into a third signal and a fourth signal, a first beamformer that synthesizes a first beamformed signal, and a second beamformer that synthesizes a second beamformed signal.
