Abstract

This article develops a novel microstrip bandpass filter with ultra‐wide stopband.With the assistance of open stubs and interdigital capacitors, a very wide stopband with a sufficient rejection level can be achieved easily. Detailed design and synthesis procedures are provided. Moreover, the electromagnetic simulator ansoft designer v3 is used, and the prototype of the bandpass filter is fabricated and measured. Good agreement between measured and theoretically predicted results demonstrates feasibility of the proposed filter. © 2010 Wiley Periodicals, Inc.

## Abstract An ultra‐wide stopband microstrip lowpass filter(LPF) for harmonics suppression is introduced in this letter. The LPF is composed of three open stubs, a pair of spur‐lines, and a pair of parallel coupled‐lines with symmetrical structure. Measured results verify that the filter has a ret

## Abstract In this paper, we propose a novel parallel‐coupled microstrip bandpass filter with a wide stopband. The proposed bandpass filter with spur lines provides a deep and wide stopband because spur lines can provide deep stopband characteristics in some frequency bands. Also, the experimental
