Design of a multi‐band asymmetric patch antennal for wireless applications

Abstract

A novel design for probe‐fed compact multiband microstrip patch antenna for wireless applications is presented in this article. The antenna is achieved by cutting the different slots' length on the patch and using unequal resonance arms. By adjusting unequal arms, various resonant frequencies are obtained. Also, this antenna presents resonance tuning ability within impedance bands by varying the length of the slots. The proposed antenna is designed and fabricated for operating at 3.66 GHz, 5.3 GHz, 5.8 GHz, and 7.03 GHz. The size of patch is 0.314λL × 0.342λL at its lower operating frequency. In addition, parametric studies are performed by investigating the effects of some key parameters on obtaining an optimal design of the proposed antenna. © 2012 Wiley Periodicals, Inc.

Design and analysis of a novel open ended T‐shaped slot loaded compact multifrequency microstrip patch antenna

“…The achieved size reduction is much better in comparison to with simple ground plane structure. The antenna proposed in this article has also achieved much better size reduction with less complex structure in comparisons to .The compact multifrequency antenna proposed in this article could be promising for a number of modern wireless communication systems due to its small size, light weight, low cost, and good working characteristics.…”

“…A number of techniques have been reported to reduce the size of a microstrip antenna. The simplest of them is by modifying the radiating patch or by modifying the ground plane . It was reported by Kuo and Wong that by embedding three meandering slots in the ground plane of rectangular microstrip patch antenna, the size of the antenna can be reduced by 56%.…”

“… for slotted edge‐fed microstrip antenna. It was reported by Malekpoor and Jam that by cutting the different slots' length on the patch and using unequal resonance arms, the size of the microstrip patch antenna can be reduced by 37% with multifrequency operation. The work presented in this article also relates to compact multifrequency microstrip patch antenna obtained by cutting an open ended T‐shaped slot on the right‐side radiating edge of the patch.…”

Bandwidth and gain enhancement of microstrip antenna by frequency selective surface for WLAN, WiMAX applications

“…The broadband was obtained by multiple number of slots loaded ground plane under the patch. In reference [3], a multi-band microstrip patch antenna was designed for 3.66 GHz, 5.3 GHz, 5.8 GHz, and 7.03 GHz wireless applications. A rectangular microstrip antenna was designed for dual frequency operation in [4].…”

A triple-band antenna array for next-generation wireless and satellite-based applications

“…The feasibility of such devices requires the use of a single-antenna element, which can provide multi-band operation, hence reducing the need of multiple antennas for each of the operating frequency bands [1][2][3][4]. Such requirements have lead researchers to explore some of the novel multi-band antenna designs [2][3][4][5][6][7][8][9][10][11][12].…”
