A novel dual-band hexagonal patch antenna coupled with complementary split ring resonator

In this paper, a novel dual-band hexagonal patch antenna coupled with complementary split ring resonator (CSRR) is proposed and analyzed. The complementary split ring resonator is etched at ground plane (underneath the hexagonal patch). It is observed from the simulation that the first band corresponds to CSRR while second band due to hexagonal patch. The proposed antenna exhibits -10 dB bandwidth of 154 MHz from 3.203 GHz-3.357 GHz and bandwidth of 180 MHz from 5.140 GHz-5.320 GHz for first and second band respectively. The average gain at the two bands is 6.70 dB and 5.42 dB.
