A novel compact Ultra-Wideband (UWB) antenna with triple band-notched characteristics is presented. The antenna patch consists of several circular rings and a small circle. The antenna has a compact size of 25 × 20 mm2, which has been printed on a Rogers RO4003 substrate. Moreover, the proposed antenna has been successfully fabricated and measured, showing broadband matched impedance (2.8 up to more than 20GHz, VSWR? 2); almost stable gain and good omnidirectional radiation patterns.
