Enhanced E- Shaped Patch Antenna for 5.3 GHz ISM Band using Frequency Selective Surface

Abstract

The proposed Microstrip E- Shaped Patch Antenna has been designed for 5.3 GHz frequency band along with FSS layer placed below the ground plane as a reflector to reduce the unwanted losses in antenna for better gain. RT Duroid is used as dielectric substrate for E-shaped microstrip patch antenna with square shaped FSS 4x4 array layer for long range wireless applications that requires higher mobility and higher data rates. It has been observed that along with FSS the gain and return loss are improved to 6.6 dB and -41 dB from 4.1 dB and −21 dB respectively. Also, VSWR have been measured by be approximately equivalent to unity in antenna with FS S from 1.16 of without FSS to 1.017 and overall bandwidth of antenna has been improved by E-shaped slots with FSS to 200 MHz. This design can be used for various wireless applications like WLAN and commercial Wi-Fi with high data rates.
