Abstract
A reflector antenna includes a reflector, a feed, and a beamforming network. The feed is spaced apart at a focal distance from the reflector. The feed includes an array of dual linear polarized elements. The beamforming network is operatively coupled to the feed. The beamforming network is configured to generate a Sigma pattern and a Delta pattern in a plane orthogonal to the reflector plane of symmetry.
