Abstract
Communication applications require wide band and highly directive planner antennas. For such requirement this work deals with the analysis and simulation of a rectangular microstrip patch antenna loaded with INTERCONNECTED SRR metamaterial structure at a height of 3.2mm from the ground plane. The work also investigates the potential properties of the proposed metamaterial structure. The proposed Antenna is designed at a operating frequency of 2.75GHz to meet S-Band (2-4GHz) applications. By loading Interconnected SRR metamaterial structure with the rectangular patch antenna at a height of 3.2mm, the antennas bandwidth is found to be increased up to 378MHz and return loss is reduced to -42.2dB i.e. the potential properties like return loss, bandwidth, directivity and total efficiency of the proposed antenna increases to a great extent in comparison to the rectangular patch antenna alone. Double Negative properties of metamaterial have been proved by Nicolson-Ross-weir (NRW) method.
