摘要：
A novel and compact planar ultra-wideband wide-slot antenna with dual band-notched function is proposed. The method of creating dual band-notch function is unique from traditional ones. By embedding a U-shaped parasitic strip and a pair of T-shaped stubs in the wide slot, dual bandstops around 3.5 GHz and 5.5 GHz can be obtained. The measured results demonstrate that the proposed antenna, with a compact dimension of 20 x 32.5 mm, has a large bandwidth over the frequency band from 2.5 to 11.7 GHz with voltage standing wave ratio (VSWR) less than 2, except the bandwidths of 3.3 similar to 3.7GHz for WIMAX and 5 similar to 6 GHz for WLAN. In addition, the radiation pattern has an excellent omni-directional characteristic in H-plane and a typical monopole-like pattern in E-plane.
