Asymmetric Shunt Inductance Iris Rectangular Waveguide Filters for Satellite Communication Systems

Abstract

This paper presents the design, simulation and manufacture of two Asymmetrical filters based respectively on standard rectangular waveguides WR90 and WR75 in which resonant irises are inserted, operating respectively in the X-Band [9-11GHz] and Ku-Band [11-13GHz].The filter parameters were simulated by the MMM modal matching method (MMM) implemented in the Microwave-Wizard software, and that obtained by the CST-MWS software. The simulated results are in good agreement with those obtained by the experimental measurements.
