A compact antenna with Coplanar waveguide (CPW) feed for WiMAX/WLAN applications is presented in this paper. Antenna is fabricated on FR4 substrate having size of (35mm×25mm).The rectangular antenna is etched with slit and stub which obtains triple band. The measured results shows that S11< ̶ 10dB impedance bandwidths are at 100MHz(2.39-2.49 GHz), 800MHz(3.4-4.2 GHz) and 1680 MHz(5.4-7.08 GHz).These frequency ranges meet the bandwidth requirement for Wireless local area network (WLAN) 2.4/5.8 GHz bands and Worldwide interoperability for microwave access (WiMAX) 3.5 GHz band. Bandwidth, S11, VSWR, radiation and gain characteristics of the antenna are investigated. Antenna exhibits good resemblance between measured and simulation results
