Microstrip Antenna using EBG Substrate

Abstract

The Performance of a microstrip antenna integrated with an electromagnetic band gap substrate is described. Electromagnetic Band Gap (EBG) substrate is used as antenna structure to improve the performance of the patch antenna. The antenna structure is made from common FR-4 substrate and operates at the 2.486 GHz wireless band. The design of the microstrip patch antenna, band gap substrate, and their integration is presented. The band gap array consists of 7x7 elements and improves the antenna gain. In this paper the antenna performance in terms of resonance frequency, return loss, radiation pattern, antenna gain, directivity, bandwidth and efficiency is observed.
