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.

A first waveguide guides a first radio wave whose electric field is vibrated in a first direction along a second direction. A second waveguide guides the first radio wave along the second direction and is cascade connected to the first waveguide. An input and output end multiplexes the first radio waves from the first and second waveguides and outputs the multiplexed radio wave, and outputs the first radio wave branched off from a radio wave from outside to the first and second waveguides. A first waveguide shift portion is shifted from the first waveguide in the first direction. A second waveguide shift portion is shifted from the second waveguide in the first direction. The vibration directions of electric fields of radio waves passing through the end parts of the first and second waveguide shift portions are rotated by 90° about a third direction.

Antenna waveguide transitions for solid state power amplifiers (SSPAs) are disclosed. An SSPA includes a waveguide channel that is configured to propagate an input signal, such as an electromagnetic signal, from an input port to a solid state amplifier for amplification. The waveguide channel is further configured to propagate an amplified signal from the solid state amplifier to an output port. Waveguide transitions to and from the solid state amplifier are bandwidth matched to the waveguide channel. Additionally, the waveguide transitions may be thermally coupled to the waveguide channel. The waveguide transitions may include antenna structures that have a signal conductor and a ground conductor. In this manner, the SSPA may have improved broadband coupling as well as improved thermal dissipation for heat generated by the solid state amplifier.
