Abstract

In this article, a bandpass filter with a wide stopband is proposed for the wireless local area network (WLAN) system. The filter is mainly composed of a dual‐mode bandpass filter (DM‐BPF) and a controllable bandstop structure (CBS). By using the CBS, multiple transmission zeros can be located on the spurious responses of the DM‐BPF. The design procedure is discussed in detail in this article. The designed filter is fabricated and measured. Measured results have a good agreement with the simulated results. © 2008 Wiley Periodicals, Inc.

## Abstract A novel dual‐mode band‐pass filter with a cross‐shaped resonator and three ring resonators has been designed and implemented. The proposed structure is different from the conventional dual‐mode band‐pass filter. The designed dual‐mode band‐pass filter has a very sharp attenuation rate b

## Abstract In this article, we propose a dual‐mode bandpass filter (BPF) at 1.575 GHz using periodic meander slotted ground structures (M‐SGSs) which are etched on the ground plane for spurious suppression. First, single M‐SGS is analyzed. Second, the M‐SGSs are used to provide a good stopband‐rej

## Abstract This paper presents the improved stopband of a novel dual‐mode bandpass filter (BPF) using an etched H‐shaped defected ground structure (DGS) at 2 GHz. The wide‐stopband characteristic results from the rejection‐band resonant characteristic of the DGS in the harmonic frequency of the du

## Abstract In this work, a novel microstrip bandpass filter with a wide stopband is proposed. With the assistance of an open stub, one modified open‐circuit coupled line with symmetrical feeding, a long transmission line, and a wide stopband with a sufficient rejection level can be achieved.
