Multiband microstrip stacked patch antenna using CSRR

In this paper, Complementary split ring resonator (CSRR) loaded microstrip stacked patch antenna is designed. The proposed antenna structure is analyzed using Ansoft HFSS and simulation results are discussed, which is based on Finite Element Method. Upper patch is designed by CSRR. This antenna shows multiband behavior, which resonates at 3.32 GHz, 5.79 GHz, 6.94 GHz and 7.45 GHz. The peak gains of the proposed antenna structure are 6.45 dB, 5.61 dB, 6.3 dB and 8.7 dB respectively.
