Abstract

To reduce the size and improve the performance, a miniature microstrip bandpass filter (BPF) is investigated in this article. On the basis of open‐loops, an interdigital capacitive load has been connected. The new design has advantages of a compact size and a large ratio of the first spurious resonant frequency to the fundamental frequency. A fabricated microstrip BPF has been validated design, and experiment results are shown in very good agreement with expectation. © 2011 Wiley Periodicals, Inc.

## Abstract A novel compact open‐loop resonator bandpass filter is proposed to suppress the spurious passband using a compensated spiral compact microstrip resonant cell (C‐SCMRC). Due to the inherently compact and stopband characteristics of the C‐SCMRC, the proposed filters shows a better spuriou
