Microstripline-Fed Printed Wide-Slot Antenna with Notch-Band for UWB Applications
نویسندگان
چکیده
A compact printed wide-slot (PWS) antenna is proposed for UWB applications. The proposed UWB-PWS antenna basically consists of a stepped microstrip feed-line with a rectangular patch stub and a rectangular wide-slot element at the aperture. Additional parasitic split-ring elements are placed along the patch stub to achieve notch-band characteristics. As the proposed antenna in absence of the ring elements offers ultrawideband performance (VSWR < 2) over the band of 2.411 GHz, the inclusion of those elements results in a notchband around 3.33.8 GHz, which covers one of the designated bands for WiMAX operations. The proposed antenna exhibits bi-directional and omni-directional radiation patterns in the Eplane and in the Hplane, respectively. In the paper, numerical results for the proposed antenna are presented. Keywordsprinted antenna; wide slot; ultra-wide band (UWB); band-notched; split-ring element

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...
