Abstract

A novel compact microstrip bandpass filter, based on open‐loop resonators with capacitive loading, is presented in this paper. The new filter has the advantages of compact size together with sharp rejection. Compared with the conventional filters using square open‐loop resonator, the proposed filter has a size reduction of 45%. A demonstration filter was designed, fabricated, and measured. Theoretical and experimental results are presented and show good agreement. © 2006 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
