A simple plasmonic based rectangular microstrip patch antenna resonating at 5.9 GHz

Abstract

In this paper, Plasmonic based microstrip patch antenna has been proposed. The proposed antenna is suitable for WLAN, Wi-Max and DSRC applications. The antenna resonates at 5.9 GHz with Return Loss of -48.47 dB and gain of 7.6 dBi. By using the metal grating; Gain, VSWR, Return Loss have been improved as compared to the conventional microstrip patch antenna resonating at 5.9 GHz. The microstrip patch antenna is constructed by using a material of dielectric constant of 3.2, tangent delta el. of 0.0025 and 1 mm height. A microstrip line is used and antenna is simulated using CST Microwave Studio.
