A compact wide band patch antenna for WLAN application

Abstract

In this paper, a design and analysis of compact probe fed slot antenna is presented. The proposed antenna has simple structure consisting Ω-shape on a rectangular patch, the overall dimension of the antenna come around 36mm×26mm×5.127mm and fed by 50Ω probe feed. The impedance matching and radiation characteristics of the designed structure are investigated by using MOM based IE3D™. The simulation results show that the antenna impedance bandwidth of the antenna reaches about 31 %(4.25GHz–5.8GHz) with return loss better than −10 dB over the chosen frequency spectrum. The proposed antenna gain of 9dBi and 7dBi are achieved. Its radiation patterns are also studied.
