Abstract

This paper presents a compact microstrip low‐pass filter with ultra‐wide stopband and sharp cutoff frequency response. The conventional shunt open‐stub filter with a slot on the ground plane has a wide stopband at high frequency, and the coupled open‐stub microstrip filter has a sharp cutoff response at low frequency. The combination of these structures gives the filter the characteristics of an ultra‐wide stopband and a prominent cutoff sharpness. © 2004 Wiley Periodicals, Inc.

## Abstract A compact microstrip dual‐plane resonant cell structure is presented. Good lowpass performance and wide stopband characteristics can be obtained with a simple single resonant cell; multiple resonant modes are introduced in the stopband, thus rejection width is significantly improved.

## 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
