In this paper a dual Uslotmicrostrippatch antenna with U shape slot cut in the groundfor wireless communication application such as WiMAX and WLAN is presented. The microstrip U shape patch antennas are gaining attenuation in various WiMAX (worldwide interoperability for microwave access) applications since last two decades. The proposed antenna is designed using FR4 substrate having dielectric constant 4.4 with microstrip feeding method. The designed antenna generates the triple frequency band of 2.40GHz,3.25GHz and 5.35GHz which can be used in industrial,scientific and medical radio band under WLAN interoperability, WIMAX and wireless networks respectively. The achieved percentage bandwidths from the designed antenna are 3.14%, 4.96%, and 2.56% respectively. It canbe seen that every U slot generates a separate resonance frequency. A bridging element is also used to shift the three frequencies to lower band. The proposed antenna is analysed using Ansoft HFSS 13 and simulated result are presented in terms of return loss,VSWR,percentage bandwidth and radiation pattern. The performance of this antenna has been analysed by modification of bridge width and slots in ground. The return loss characteristic for triple bands are -31.8dB at 2.40GHz,-25.12dB at 3.25GHz and -31.34dB at 5.35GHz respectively which suggest good antenna performance.
