Stepped Impedance Waveguide Bandpass Filter at Ku Band with Coupling Routing Diagram

Abstract

A waveguide band pass filter is designed with different impedances operating at KU band (12GHz-18GHz) by using finite element method and the corresponding coupling routing diagram was developed. A 17^th order waveguide band pass filter is designed using the stepped impedance method and the filter structure is drawn for same electrical lengths by varying their widths and heights. Return loss and transmission coefficient are obtained from the simulations for this waveguide bandpass using finite element method An-soft HFSS.
