Abstract
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 size of 20X32.5 mm, has a large bandwidth over the frequency band from 3.1 to 10.6 GHz with voltage standing wave ratio (VSWR) less than 2, except the bandwidths of 3.3~3.7 GHz for WIMAX and 5~6 GHz for WLAN. In addition, the radiation pattern has an excellent omni-directional characteristic in the H-plane and a typical monopole like pattern in the E-plane.
