Abstract

In this article, a novel trisection cross-coupled filter with symmetrical response by using split-ring resonator defected ground structure (SRR DGS) is presented. The SRR DGS is loaded at the bottom of a two-pole microstrip SRR filter, then a compact trisection cross-coupled filter with a pair of transmission zeros is obtained. A practical filter which has a center frequency of 1.4 GHz and a relative bandwidth of 14% is successfully designed and fabricated.
