Design and analysis of metamaterial unit cellultra-wide band triangular antenna for C band applications

Abstract

This works discuss about the design and development of a metamaterial triangular micro strip ultra-wideband antenna for C-Band communication. This study includes design and performance analysis of patch based antenna to serve C-band applications such as satellite communications. In first scenario, simple triangular antenna with normal ground plane has designed and analyzed. And In second scenario, to improve the antenna radiation, ground has altered and replaced with a unit cell structure. To further improve the antenna performance Split Ring Resonators are incorporated along with radiating patch. In these three different scenarios, antenna performance has been improved from first scenario to last scenario, while dimension of antenna got miniaturized, which is most desirable feature. The antenna gain of antenna in three scenarios is 4.96 db, 5.65 db and 6.15 db respectively. Antenna radiates over 6-7 GHz frequency band in first case, whereas in second scenario it radiates from 5.7 – 7.1 GHz and in third scenario antenna radiates at 5.6-7.4GHz band. This antenna can be placed in limited space.
