Compact multiband rectangular antenna for wireless communication

Abstract

Compact multiband cross slot rectangular microstrip patch antenna is introduced in this paper. Here one close ended rectangular slot in ground plane and one cross slot in patch are given to excite different resonant frequencies. The correct probe feed location along with the exact slot position gave the promising result. The proposed antenna meets the requirement of impedance bandwidth, return loss and gain of resonant band for IEEE 802.11a and IEEE 802.11b WLANs application that allocate channels in 2.5GHz and between 5.15 to 5.825 GHz.
