Abstract

A single feed compact rectangular microstrip antenna is presented in this paper. Two L slots are introduced at the edge of the patch to reduce the resonant frequency. The antenna size has been reduced by 71.14 % when compared to a conventional square microstrip patch antenna with a maximum of 48.56 MHz bandwidth and #x2013;30.6 dB return loss. The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. An extensive analysis of the return loss, radiation pattern and efficiency of the proposed antenna is shown in this paper. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication and make it suitable for the applications in Wireless communication system. Mainly it is developed to operate in the WiMax frequency range of 2.5-2.69 GHZ
