摘要：

A differentially driven ultra-wideband (UWB) polarisation diversity antenna with dual notch bands is presented for the first time. The antenna consists of a chamfer square slot and two differential pairs being orthogonal to achieve polarisation diversity performance over the UWB. The proposed antenna has a wide impedance bandwidth from 2.75 to more than 11 GHz for differential reflection coefficients less than -10 dB, and a high differential port-to-port isolation of less than -40 dB. Dual band-rejected operation to filter the 3.5 GHz WiMAX and 5.5 GHz WLAN bands is obtained by employing two different methods. All these features make the proposed antenna very suitable for applications in UWB wireless communication systems.
