Improvement in Parameters of Patch Antenna by Using â�?�?Spiral Shapesâ�? Metamaterial Structure

Raj Kumar Prajapati and Satyandra Singh Lodhi

In this work, a Rectangular microstrip patch antenna loaded with “Spiral Shaped” metamaterial structure is designed at a height 3.2 mm from the ground plane by using CSTMWS software. The resonance frequency of the designed antenna is 2.1GHz.The 10 dB impedance bandwidth of proposed antenna is 35.1 MHz the Return loss of the proposed antenna is reduced by 35 dB .This antenna is small size, cheap, compact and easy to fabricate, and achieve good radiation characteristics with higher return loss. This antenna can have wide application in a great variety of wireless communication.
