Design and Analysis of Wide-Band Planar Antenna using Meta-material for S-Band Applications

Abstract

A meta-surface inspired patch antenna is proposed and studied for S-band Applications. The proposed antenna has single fed configuration is loaded with an array of meta-surface unit cells for miniaturization and improve the performance of bandwidth. The detailed antenna radiation characteristics are examined and illustrated with simulated results. The antenna is designed for S-band frequency 2.5GHz on FR4 substrate having dielectric constant 4.4 and loss tangent of 0.02 and simulated using Ansoft HFSS software. The simulated results obtained are 10.4% (2.34-2.62 GHz) for 10 dB return loss bandwidth which is 4% more than antenna without meta-surface, 6.7 dBi for gain performance and patch size reduction up to 29% using meta-surface. This antenna will be applicable for S-band Radar applications such as weather radar, surface ship radar and space borne radar (SAR) etc.
