Abstract

The re‐entrant coupling structure is applied in a parallel‐coupled microstrip filter design to ensure a wide bandwidth, compactness, and the suppression of spurious. Fan design graphs are provided to determine the dimensions of each coupled stage. The features and advantages of the proposed circuit are analyzed in detail. Two experimental filters with design bandwidths of 70 and 90% are fabricated to verify the effectiveness of the modified structure. © 2009 Wiley Periodicals, Inc.

GHz are for the notch frequency and the radiation patterns at 3.96 and 8.18 GHz are for the passband frequency. The measured radiation patterns at the passband frequency are about the same for the antenna both with and without the U-slot. The measured results show that the radiation patterns in the

## Abstract Defected‐ground coupled microstrip lines (DCL) bandpass filter is proposed. The length of the proposed filter is quarter the length of conventional coupled‐line filter and it has a wide stopband and suppressed spurious resonances up to 4f~0~, where f~0~ is the filter central frequency.

## Abstract It is an important issue to suppress the spurious response of the coplanar‐waveguide (CPW) bandpass filter (BPF). In this letter, a novel CPW BPF at 1.57 GHz with spurious responses suppression for application in Global Positioning System is presented. By adjusting the filter structure,

In this paper, three methods to reject the first spurious harmonic in parallelcoupled microstrip filters are investigated. The authors proposed an extension of these approaches to also suppress the second unwanted passbands while keeping the initial passband practically unchanged. Then, two of these

## Abstract In this article, a novel and compact hairpin bandpass filter (BPF) using defected ground structure (DGS) is discussed. By placing a novel cascaded z‐slot DGS at the location of the input and output port, the first spurious passband can be rejected. The elaborate analysis of the z‐slot D

## Abstract In this paper, a wide rejection bandwidth bandpass filter with stepped‐impedance hairpin (SIH) resonator and interlaced coupled‐line was proposed. With the former, its elliptic‐function low‐pass response was adopted to steepen the upper roll off characteristic and flatten the rejection
