Miniaturization of Microstrip Patch Antenna Using Metamaterial

Ranjit Varma, S. K. Sharma, Birbal Singh

Miniaturization of Microstrip patch antenna has been proposed using “H shaped interconnected Split Ring” Metamaterial antenna. Proposed Metamaterial antenna reduces the size of the Microstrip Patch Antenna substantially and increases the directivity. The proposed Metamaterial structure along with Microstrip Patch Antenna exhibits -32.55 db return loss at 2.865 GHz. The design and simulation of Microstrip Patch Antenna with and without Metamaterial structure has been done using CST software. Then antennas are fabricated and their properties are measured using Spectrum Analyser. Double Negative property of Metamaterial structure has been proved here using Nicolson Ross Weir approach.
