Compact multiband monopole antenna for WLAN/WiMAX applications

Abstract

In this article, a compact multiband monopole antenna is proposed to cover the frequency band for wireless local area network and worldwide interoperability for microwave access application. The multiband monopole antenna has the advantage of compact size of 15 × 30 mm2. The proposed antenna is an S‐shaped strip connected with a notched rectangle loop radiation patch with a ground plane, and there is a slot in the ground plane. The two lower bands are achieved by the rectangle loop patch and the higher band is achieved by the slot in the ground plane. The impedance bandwidth for 10 dB return loss at 2.46, 3.8, and 5.4 GHz, are from 2.4 to 2.51 GHz, 3.20 to 4.07 GHz, and 5.08 to 5.85 GHz, respectively. Experimental results show that the antenna gives omnidirectional radiation patterns and stable antenna gains in the operating bands with the compact size. © 2014 Wiley Periodicals, Inc.

Yeni Bir Melez Optimizasyon Algoritması Kullanarak UMTS, WLAN ve WiMAX Uygulamaları için Çift–Geniş Bantlı Monopole Anten Tasarımı

“…Additionally, these antennas have been widely utilized in wireless communication applications to meet the multiband, wideband applications and size reduction operations. So far, numerous microstrip antennas have been proposed to reduce size, enhance bandwidth, obtain multiband characteristic [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Two different coplanar waveguide (CPW) fed monopole antennas embedded slots into the patch and ground plane have been reported for operating in WLAN [1,2].…”

“…In [11,12], the two microstrip antennas which have different geometries for WLAN and WiMAX have been presented to produce dual resonant modes, respectively. The novel microstrip antenna designs [13][14][15][16] with different geometric shapes have been investigated to achieve multiband operation covering the frequency bands of WLAN and WiMAX. In Ref.…”

“…In addition, most of these antennas do not cover whole frequency bands of WLAN and WiMAX. [1,2,[4][5][6][7][8][9][11][12][13][14][15][16][17].…”

“…The designed antenna is then fabricated and measured to evaluate the performance achievable. A successful comparison of the proposed antenna with the antennas previously published in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] is carried out with respect to operating frequency and bandwidth.…”

A Compact Dual-Band Printed Monopole Antenna for Wimax/Wlan Applications

“…As one of the most important devices, multi-band antenna has attracted much interest. To cover desirable bands and reduce the size, various promising antennas, such as printed monopole antenna [1][2][3][4][5], CPW-fed antenna [6,7], slot antenna [8][9][10], inverted-F antenna [11], have been proposed. For example, an printed monopole antenna of size of 38 × 25 mm 2 was developed in [1], its triple-band operation was achieved by a circular ring, Y-shape-like strip and a defected ground plane.…”
