In this paper, the design and implementation of a co-axial feed U-slot microstrip antenna for 5.5GHz WLAN application is presented. The VSWR (Voltage Standing Wave Ratio) and the return loss of this proposed structure are studied and analyzed using Computer Simulation Technology (CST) microwave studio, it's based on the method of finite difference time domain techniques to achieve the desired specification. The proposed antenna based on co-axial feed configuration has the maximum achievable bandwidth obtained about 260MHz (5.36-5.62GHz) at -10db reflection coefficient which corresponds to WLAN 5.5GHz frequency band and maximum achievable gain is 5.3db at 5.5GHz center frequency.
