WAVEGUIDE HYBRID COUPLERS

Abstract:

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.
