Abstract
In this article, a new multi-resonance slot antenna, with dual band-notched performance for UWB applications is presented. In the proposed structure, by cutting a rotated C-shaped slot on top of the ground plane, additional resonances are excited and hence much wider impedance bandwidth can be produced, especially at the middle band. To generate single band notch characteristics, we use a rotated C-shaped parasitic structure in the ground plane. Also to achieve dual band notch function, we insert a rotated C-shaped slot at square radiating stub. The measured results reveal that the presented dual band-notched slot antenna offers a very wide bandwidth with two notched bands covering all the 5.2/5.8 GHz WLAN, 3.5/5.5 GHz WiMAX, and 4 GHz C bands. © 2013 Wiley Periodicals, Inc.
