Abstract

A ridged-waveguide diplexer incorporating integrated compact ridged-waveguide filters and a ridged-waveguide T-junction is presented. The compact size of the filter is achieved by integrating a bandpass periodic filter, and a low-pass structure is used in order to suppress spurious responses. Simulation using the mode-matching method has been carried out for ridged-waveguide filters and T junctions and the results are presented. The measured results are in good agreement with the simulated results. © 2004 Wiley Periodicals, Inc.
