In this paper, a quad-band antenna with circular patch antenna loaded with annular ring with CSRR DGS is presented. To improve the impedance bandwidth, a meander line structure is etched on the patch and complementary split ring resonator (CSRR) structure on ground plane of the antenna. The proposed antenna has resonated at quad-band for wireless applications. The operating frequencies are observed at 2.31 GHz, 3.05 GHz, 4.69 GHz and 5.6 GHz with reflection coefficients −9.47 dB, −22.80 dB, −18.87 dB and −25.27 dB, respectively. The gains at the resonating frequencies are 2.67, 3.74, 4.5 and 4.31 dB. The radiation patterns are also presented. The obtained frequency bands are suitable for wireless applications like WiMAX, WiBro and WLAN.
