A compact micro-strip patch antenna with a slot fed by coaxial probe is presented in this paper. The slot which is circular in shape with triangular truncations results three narrow bands. The patch is designed on FR4 substrate of thickness 1.6 mm and relative permittivity of 4.4. The size of the proposed antenna is 35mm x 45mm x 1.6mm. Return loss comparison is done for different feed locations. The proposed antenna is suitable for WiMax, Wi-Fi and WLAN applications. The simulations are carried out using Finite Element Method based Ansfot High Frequency Structure Simulator (HFSS).
