Abstract：A triple-band printed micro-strip antenna fed by coplanar waveguide (CPW)is designed based on notched structure.The character of multi-band is achieved by adding slots to the radiation patch and micro-strip of planar monopole antenna.The antenna model is simulated and optimized by electromagnetism simulation software HFSS12 and a prototype is manufactured according to the result of simulation.The re-sult of measurement fits well with that of simulation.The antenna can work on the bands of 1.85~2.53 GHZ,3.14~4.38 GHz and 4.87~5.93 GHz (S11<-10 dB),which cover the bands of Bluetooth (2.4~2. 48 GHz),WiMAX (3.4~3.6 GHz)and WLAN (5.15~5.825 GHz).The antenna’s impendence and gain are good enough to meet the requirement of wireless communication in its working bands.
