Abstract :

A new air gap aperture coupled design is proposed for microstrip slot antennas to improve their bandwidth. The proposed design is based on a new aperture coupling technique in which slot is fed by microstrip line and coupled to patch radiators etched on the opposite side from the slot. The coupling slot is H-shaped slot. This paper presents design and simulation results of air gap aperture coupled microstrip antenna. The -10dB return loss bandwidth of the air gap aperture coupled antenna is 920MHz which is about 15.86% (from 5.42GHz to 6.34GHz )of the center frequency at 5.8GHz.This band is used in wireless LANs, cordless phones and HIPERLAN applications. The peak gain at the center frequency is about 8.03dB.The antenna is modelled using Ansoft HFSS (high frequency structure simulator) software
