A compact dual-band planar antenna with high gain for WLAN application is presented. The antenna fed by CPW is composed of T-type feed and double C-type meander line, which generate the higher and lower operation bands respectively. DGS structure in CPW ground broadens the bandwidths of high frequency. Through electromagnetic simulator software simulation and analysis, the overall size is 30×15.25×1.6mm. The simulation results show that the proposed antenna can operate in 2.35∼2.52GHz and 3.85∼6.14GHz, which cover the WLAN operating bands of IEEE 802.11n and 802.11a/b/g. The gain is 1.42dBi at 2.45GHz, and 4.42dBi at 5.2GHz, and 5.38dBi at 5.8GHz, respectively. The radiation patter of the antenna is omnidirectional and has higher gain.
