| Popis: | In this letter, a novel printed monopole antenna for ultra wideband applications with variable frequency band-notch characteristic is presented.The proposed antenna consists of a forked-shaped radiating patch with an inverted T-shaped parasitic structure and a ground plane with a pair of G-shaped slots, which provides a wide usable fractional bandwidth of more than 130% (2.9–14.1 GHz). To generate frequency band-stop performance, the forked-shaped strips are folded back and result in a pair of coupled lines on the radiating patch that we can control band-stop performance characteristics such as band-notch frequency. By inserting an inverted T-shaped parasitic structure on the radiating patch and also by cutting a pair of G-shaped slots with variable dimensions on the ground plane, additional resonances are excited and hence much wider impedance bandwidth can be produced, especially at the higher band. The designed antenna has a small size of 10 × 16 mm2 while showing the band rejection performance in the frequency band of 5–6 GHz. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the UWB frequency range. © 2012 Wiley Periodicals, Inc.
