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 3.5GHz and 5.5GHz can be obtained. The measured results demonstrate that the proposed antenna, with a compact dimension of 20 × 32.5mm, has a large bandwidth over the frequency band from 2.5 to 11.7GHz with voltage standing wave ratio (VSWR) less than 2, except the bandwidths of 3.3 ∼ 3.7GHz for WIMAX and 5 ∼ 6GHz 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.
