A method and apparatus forming an efficient and compact waveguide feed with all components for processing signals in multi-frequency band antenna feeds with single/dual linear/circular polarizations with/without tracking. This layout results in a very compact feed, which has excellent electrical characteristics, is mechanically robust, eliminates flange connections between components, and is very cost effective. The new layout eliminates the dummy ports and bends at least one filter element is bent to an acute angle, thereby enabling a high density packaging of the microwave feed network; and wherein a plurality of single sided corrugations are located along the bent filter element. In this design high density arrays of feeds can be realized for satellite communication.
