Abstract

A novel bandpass filter using double‐sided parallel‐strip line (DSPSL) is proposed in this paper. Based on the differential characteristics of DSPSL, the proposed filter has a wide stopband up to the third spurious resonance frequency. Also, this filter can achieve high power‐handling capability because the linewidth of DSPSL is wider than that of microstrip with the same characteristic impedance. A demonstration filter was designed, fabricated, and measured. Theoretical and experimental results are presented and show good agreement. © 2007 Wiley Periodicals, Inc.

## 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

## Abstract This letter proposes a parallel coupled‐line bandpass filter (BPF) using the folded slotted ground structures (SGSs) to improve the wide stopband. It is shown that the designed folded SGS has a very small area in comparison of previous works. The folded SGS exhibits a dual stopband char

## Abstract This article presents a dual‐mode dual‐band bandpass filter based on double‐sided parallel‐strip line with an inserted conductor plane. Due to the isolation property of the conductor plane, this structure can provide two separate transmission paths to generate two passbands. No extra co
