In this paper, an application for a monopole antenna which complies with worldwide interoperability for microwave access (WiMAX) is presented. The proposed antenna operates in the frequency range of 3.43-3.61 GHz applicable for WiMAX. The antenna is fabricated on FR4 plate of 33.25 x 33.25 x 1.6 mm3. The performance of the antenna is analyzed in terms of radiation pattern, gain and s-parameters. The s-parameter of the antenna are verified through measurements. The obtained results illustrate that the presented antenna has better characteristics in terms of operating band as well as return loss as compared to the antennas previously published in the literature.
