N2 - In this paper, a new Ultra-wideband (UWB) antenna with triple band-notched characteristics is presented. The antenna is composed of a semicircular radiator ended with trapezoidal structure, a rectangular ground plane, and occupies a compact structure of size 30 × 30 mm2. By employing a parasitic strip in the backside of the radiator, etching a pair of inverted-L slots on the ground plane and introducing novel asymmetrical resonators alongside the feed line, three rejected bands are obtained. The proposed antenna provides an extremely wideband width ranging from 3.0 GHz to 12 GHz (|S11|<−10 dB), except the tri-rejection bands of 3.39–3.88 GHz, 5.11–5.97 GHz, and 8.0–8.71 GHz. Furthermore, the antenna achieves a square shape in the second notched band. In addition, cross polarization, radiation patterns and moderate gains are also investigated. Good agreement is obtained between the measurement and simulation, indicating the antenna is promising for UWB applications.
