A compact full mode SIW UWB Band pass filter using novel input/output transmission-line-stnicture

Abstract

A compact fullmode SIW UWBband pass filter using novel input/output transmission-line-structure is proposed in this paper. This wide band SIW resonator can be evolved from a conventional SIW transmission lineor a two-conductor transmission line. This filter has wide passband of 3–8GHz with return loss of nearly −20dB.
