The dual U-slot and tri-U-slot patch antennas have been designed to operate in WiMAX and WLAN applications. The radiation parameters such as return loss, radiation patterns, VSWR, and gain of the antennas have been analyzed using CST microwave studio. The proposed antennas have simple structure, simple coaxial feed, inexpensive, ease of fabrication and light weight designed for realizing dual band characteristics. The dual U-slot antenna has the bandwidths of 0.27GHz and 0.47GHz ranging 3.37GHz to 3.64GHz and 5.15GHz to 5.62GHz respectively. The tri-U-slot antenna has the bandwidths of 0.14GHz and 0.66GHz ranging from 3.61GHz to 3.71GHz and 5.18GHz to 5.84GHz respectively. The gains of the dual U-slots antenna have 8.77dBi, 9.47dBi and 8.1dBi and tri-U-slot antenna have the gains of 8.71dBi, 8.66dBi and 9.09dBi at the operating frequencies of 3.67GHz, 5.2GHz and 5.8GHz respectively. The simulated and measured results show that the antennas have stable gains, good impedance matching and directional radiation patterns. The measured and simulated results are in good agreement.
