A TE20 launch guidance waveguide hybrid coupler includes a waveguide body, a cavity, a plurality of ports, and a bend along the H-plane. The waveguide body includes a hybrid center portion which is disposed between and is in direct communication with the plurality of ports. The bend along the H-Plane is defined within the hybrid center portion, assists in the launching of the TE20 mode, and results in typically half the axial ratio and mass when compared to traditional hybrid approaches.

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.
