Effect of EBG Presence on Elliptical Patch Antenna T maheshwar1, ch shekar2, p aruna3 1,2,3 Department of Electronics and communication Engineering,SreeDattha Institute of Engineering & Science Abstract: The Paper demonstrates the design and performance of Elliptical Patch antenna in presence of EBG structure at one of its sides and its performance is compared with conventional type under similar design conditions. Here the designed Elliptical Patch antenna has a major radius 4 and ratio 30. And EBG designed as single layer of one array of patches for EBG and having 0.5cm pillar height patch size of 2cm side length square shape patches with 0.2cm gap. Conventional antenna operated at a frequency of 2.6608GHz and in presence of EBG it works at 2.6683GHz Frequency and the comparative analysis is illustrated in this paper. Keywords: Energy Band gap Structure (EBG), Surface Wave Suppression, Radiation Enhancement, improved gain. I.INTRODUCTION The micro strip patch antennas have their various advantages in wireless communication applications because of their low cost manufacturing, compatibility with low size, and these micro strip antennas are low profile antennas. But still these antennas have narrow band width and its radiation enhancement is much needed for improvisation of its usage in our communication applications. Here I use EBG structures to enhance the antenna parameters. Generally the EBG structures mainly suppresses the surface wave propagations many researches concentrated on using this EBG in various methods to enhance the antenna parameters and to check its effects on Conventional antennas here in this paper we analyse the Elliptical Patch antenna and compare its radiation pattern width, gain directivity, intensity, front to back ratio and Radiation efficiency with conventional type. Fig [1]. Conventional and Designed antenna II. ANTENNA AND EBG DESIGNS 1.1. Antenna Here the same elliptical patch antenna is used for the analysis on same substrate under same execution conditions. The designs or shown in the below figure [1]. And the antenna is fed with micro-strip feed from wave port for excitation.
