Abstract

This paper proposes the design of wide bandpass filters for Ku and Ku/K band applications. It has wide passband with miniaturization of size using folded substrate integrated waveguide (FSIW) technique. The filter is designed by introducing a C slot and an E slot in central metallic septum of FSIW respectively. The proposed filters are fabricated and tested after optimization. The fabricated E slot filter achieved enhancement in bandwidth with dual band operating in Ku band (14.35 GHz-16.76 GHz) and K band (18.66 GHz-19.61 GHz), respectively. The measured results match quite closely with simulated ones.
