This paper presents a single element rectangular microstrip patch antenna for worldwide interoperability for microwave access (WiMAX) applications. This antenna was designed to obtain high directivity with better gain and minimum return loss. The proposed antenna was designed for 2.5GHz frequency using Computer Simulation Technology (CST) software and then fabricated using copper material for the ground plane, patch, and feeding part and Isola FR408 material for the substrate. In experiments, the proposed antenna was tested using simulation parameters and a network analyzer. The proposed antenna was tested at different frequencies, including 2.5GHz, 4.5GHz, and 9.1GHz. The performance of the proposed antenna was measured in terms of return loss, gain, and directivity. Experimental results demonstrated that the rectangular patch antenna provided a return loss of –25.16dB at 2.5GHz with the use of a dielectric substrate with a Ɛr value of 4.4 and 1.5 mm height. Also, the gain of the antenna was 4.4144dB. Moreover, the resonant frequency of the designed antenna ranged from 2 to 4GHz, which is suitable for WiMAX applications.
