A new dual-frequency broadband antenna applied to WLAN/WiMAX is proposed. By using the ways of slotting symmetrical inverted F-shape notch in the rectangle radiation patch and symmetrical L-shape notch on the reverse-side earth plate,this antenna has better dual-frequency broadband characteristics. The impedance bandwidth of the actual measurement an-tenna are 700 MHz(3.2~3.9 GHz)and 1.5 GHz(4.8~6.3 GHz),and can cover the bands of 3.5 GHz WiMAX and 5.2/5.8 GHz WLAN. The maximum gain of the antenna at the dual-frequency working point are 2.508 dBi and 3.645 dBi respectively. This an-tenna has good omnidirectional radiation characteristics. The test results show that the design method is valid.
