In this paper a compact wideband dual-frequency microstrip antenna is proposed. By arranging two parallel slot on proximity coupled equilateral triangular microstrip antenna(PSPCETMSA) operating at dual frequency at 3.07 and 6.22 GHz with the impedance band width of 10.49% (311MHz) and 5.37% (333MHz) respectively is presented, which is suitable for Mobile Wimax (Worldwide Interoperability for Microwave Access) IEEE 802.16 and Fixed Wimax IEEE 802.16 applications. The antenna gives broadside radiation characteristics at each resonating frequency. This antenna is simulated by using Ansoft HFSS electromagnetic simulation software. A design concept of the antenna is given and simulated results are presented and discussed.
