Design of an UWB power splitter of arbitrary split ratio using asymmetrical double ridge waveguide

An asymmetrical double ridge waveguide is used to develop power splitter/combiner with arbitrary power division ratio. The power splitter is inherently wide band covering the whole band of the waveguides. The splitter can have a very short length and needs the same width as the input waveguide. It has a highly constant coupling value with return loss better than 25 dB. Results of a 10-dB power splitter are presented as an example.
