摘要

A planar differential-fed antenna with dual band-notched characteristics is presented for ultra-wideband (UWB) applications. The proposed antenna mainly consists of two V-shaped radiating patches placed face to face and an octagonal slot ground plane. To avoid the potential electromagnetic interference from narrowband services, V-shaped slots embedded in the radiating patches are adopted to reject 5.5 GHz WLAN band, while T-shaped stubs connected with the radiating patches are introduced to filter 8 GHz ITU band. A prototype of the proposed antenna is fabricated and tested. Measured results demonstrate that the obtained impedance bandwidth is from 2.82 to more than 11 GHz, along with two notched bands of 4.83-6.12 GHz and 7.86-8.57 GHz. In addition, the proposed antenna exhibits good radiation patterns and stable gain.
