Abstract
A modular beamformer system for providing signals to at least two radiating elements of a phased array antenna is provided. The system includes a right-hand circular polarization beamformer module and a left-hand circular polarization beamformer module. The left and right circular polarization beamformer modules are coupled to two radiating elements. Each beamformer module includes two groups of beamforming circuitry, one per radiating element. At least one feeder line extends from each beamforming circuitry and is coupled to one of the radiating elements to transmit an output of each beamforming circuitry.
