Dual-Wideband Symmetrical G-Shaped Slotted Monopole Antenna for Wlan/Wimax Applications

Abstract

A novel dual-wideband printed monopole antenna is proposed for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The proposed antenna consists of a T-shaped monopole on top and dual combined G-shaped slots etched symmetrically on the ground plane to achieve a dual-wideband performance. Prototype of the proposed antenna has been constructed and tested. The measured 10 dB bandwidths for return loss are 1.76 GHz from 2.13 to 3.89 GHz and 0.92 GHz from 5.03 to 5.95 GHz, covering all the 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5 GHz WiMAX bands. And this antenna also has omni-directional patterns over the lower operating range.

Design of CPW-Fed Strips Patch Antenna for Wireless Communication Applications

“…The fast growing WLAN protocols operating bands are at 2.4 GHz (2400-2484 MHz), 5.2 GHz (5150-5350 MHz) and 5.8 GHz (5725-5825 MHz), the operating bands of WiMAX is 2.5/3.5/5.5GHz (2500-2690/3400-3600/ 5250-5850 MHz) bands. Multi-band antennas with simple structure and superior radiation performance for WLAN/WiMAX applications have been increasingly appealing [4][5][6][7][8][9][10]. These antennas usually cover the WLAN 2.4/5.2/5.8 GHz and WiMAX 2.5/5.5/5.8 GHz bands.…”

Wideband G-Shaped Slotted Printed Monopole Antenna for WLAN and WiMAX Applications

“…Therefore, various types of antenna have been reported in literature to operate along the WLAN and WiMAX frequency bands [1][2][3][4][5][6][7][8][9]. Different techniques have been proposed providing dual, triple or four band performances such as parasitic inverted U-shaped [1], paw shaped [2], C-and L-shaped [3], split ring slot [4], Tshaped [5] and umbrella printed dipole [6]. Furthermore, a coplanar waveguide (CPW) fed monopole antenna [1], coupling fed plate [7] and defected ground plane [5,8] are other methods have been used to improve the impedance bandwidth of the antenna and simultaneously improved the antenna performance.…”

In this article, a wideband G-shaped slotted bandwidth of 95.1% compared to others value that resulted dual band and decreased the relative bandwidth performances.…”

Design of Tri-Band Printed Monopole Antenna for Wlan and Wimax Applications

“…Furthermore, they also have the advantages of low profile, simple structure, easy fabrication, and good monopolelike radiation pattern. Many dual-wideband and wideband printed monopole antennas have been proposed in [1][2][3][4][5][6][7] for WLAN and WiMAX applications. However, when these antennas are used in WLAN and WiMAX systems, additional band pass filters are required to avoid collision and minimize frequency interference because their wide operating bands cover many existing narrowband services.…”
