Development of C band Patch Antenna for WLAN and Satellite Applications using Metamaterial

Abstract

The Microstrip patch antenna with metamaterial is proposed. The use of metamaterial in the antenna reduces the size of antenna and also improves other antenna parameters such as improving the return loss and efficiency. The complementary split ring resonator (CSRR) is loaded on the radiating patch antenna due to which multifrequency response is also obtained. Flame Retardant (FR4) epoxy substrate is used. The proposed antenna operates at 4.1GHz, 5.27GHz and 7.6GHz having bandwidths of 6.7%, 10.3% and 8.15%. The structure is simulated using High Frequency Structure Simulator (HFSS).
