Abstract

A reduced‐size low‐loss high‐selectivity wideband microstrip bandpass filter is proposed using three λ~g~/4 short‐circuited stubs and folded λ~g~/2 connecting lines between them. The filter has 2__n__ − 1 poles within the passband, whereas it consists of only n resonators. The 3‐dB bandwidth of the filter is about 92% at 2.1 GHz. The insertion loss is around 0.8 dB within the passband. The filter is verified by both simulation and measurement. © 2005 Wiley Periodicals, Inc.

## Abstract The transmission characteristic of the microstrip with complementary split ring resonator (CSRR) is researched. Compared with the conventional structure, this filter can achieve a wider bandgap by shifting the gap of CSRR from the side of the microstrip to the underside. And then, a low
