WIDEBAND SINGLE PATCH E-SHAPED COMPACT MICROSTRIP ANTENNA FOR HIGH SPEED WIRELESS LOCAL AREA NETWORKS

This paper presents a single wideband E-shaped compact microstrip antenna for high speed WLANs operating in the 5 – 6 GHz range. By using only single patch a high impedance bandwidth is achieved. The simulated impedance bandwidth (VSWR<2) is 25.9%, and measured bandwidth is approximately equal to 24.85%. This prototype antenna has a gain of 8.5 dB. The back radiation lobe is also > 20 dB. This antenna is fed by a co-axial probe feeding. In this paper, the effects of different parameter of antenna are also studied.
