Multiband printed and double‐sided dipole antenna for WLAN/WiMAX applications

Abstract

A novel type of printed and doubled‐sided dipole antenna with multiband operation for wireless local area networks and worldwide interoperability for microwave access is presented. The antenna is composed of several symmetrical branch strips dipoles which are employed as resonators for multiband operation and a modified rectangular ground plane as a reflector. Prototype of the proposed antenna has been constructed and experimentally studied. The measured results of the tri‐band not only explore wide −10 dB impedance bandwidths of 20, 14, and 15% at the operating bands of 2.5, 3.5, and 5.5 GHz respectively, but also show good agreement with the numerical predictions. © 2012 Wiley Periodicals, Inc.

A Compact Microstrip Slot Antenna With a Pair of Inverted L-Strips and Elliptical-Arc-Shaped Stub for Wlan/Wimax Applications

“…Compared to many antennas proposed in recent papers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], this antenna is designed based on a rather simple structure and suitable for all the WLAN/WiMAX frequency bands. By introducing a pair of symmetrical inverted L-strips and an elliptical-arc-shaped stub, the proposed antenna can generate two separate resonances at 3.5 and 5.5 GHz, while the trapezoid and ellipse slot on the ground plane is to excite the lowest resonant mode.…”

“…Owning to these merits, several promising types of dual-band and multiband antennas have been reported in the recent literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. For example, many printed monopole antennas with different shapes have been presented, including a printed symmetrical Gshaped antenna [1], a printed double-T-shaped antenna [2], an Lshaped and E-shaped antenna [3], and a planar antenna with a shorted parasitic inverted-L wire [4].…”

“…But the radiation performances of these antennas are not so good especially in the upper band because of the asymmetric structures. In [12][13][14][15], although the antennas have good radiation characteristics and reasonable compact size for both WLAN and WiMAX systems, they are somewhat complicated in structures.…”

“…Usually, the structure of the conductingradiating patch of the antenna can be anyshape. In practice, rectangular, elliptical, square, circular, triangular shapes are considered for antenna design [13][14][15][16][17][18][19]. The ability to provide an antenna small size is an important requirement for the design and development of multiband operation.…”

“…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].…”
