Microstrip‐CPW bandpass filter for antenna application

Abstract

This article presents a quasi‐lumped bandpass filter with CPW‐microstrip ports. The structure serves as CPW‐microstrip transmission in addition to its filtering function. The filter was integrated with a microstrip patch antenna. To enable the filter design, the characteristic impedance of the slotted microstrip line and the coupling strength of microstrip to microstrip, CPW to CPW and microstrip to CPW transitions were calculated. © 2007 Wiley Periodicals, Inc.

A compact filter‐combined ultra‐wide band antenna for UWB applications

“…Parametric studies and radiation characteristics for this antenna are presented. Ansoft high-frequency structure simulator (HFSS) [10] is used to simulate the proposed antenna. Prototypes of the proposed antenna have been successfully implemented.…”

“…In [9] to notch the WLAN and Hyper LAN service bands (5.15 to 5.825 GHz), a compact band-selective filter and antenna for UWB application was proposed. A narrow band-pass filter is integrated with the patch antenna to serve as a transition between the CPW feed and a microstrip patch antenna and also to cut the higher order patch resonances [10]. In this paper, we will focus on the design of a compact filter-combined ultra wideband antenna operating in the frequency range of 3.1-5.2 GHz (DS-UWB low band or MB-OFDM lower three bands).…”

Filtering wideband slot antenna using split-ring resonator

“…There is mutual coupling when the antenna cascades with filter, which could deteriorate the performance of antenna and filter. Nowadays, collaborative design methods of antenna and filter are becoming attractive, namely, filtering antenna [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. A dual-band filtering antenna is reported in [15].…”

Novel and compact open-ended CRLH-TL notch filter

“…One of the methods to do this is to use notch filters for the particular frequency band. Numerous methods have been adopted to design notch filters . The open‐ended quarter‐wavelength stub is one of the easiest ways to apply, but it results in a larger size at the lower frequency band less than 1 GHz.…”
