Abstract
A compact tracking coupler includes a plurality of ridged waveguides arranged circumferentially around a circular waveguide wherein long sides of the ridged waveguides extend circumferentially and short sides of the ridged waveguides extend radially relative to the circular waveguide. The compact tracking coupler can be especially useful in a multi-band antenna feed.
