Novel Wide-Slot Antenna with Traveling-Wave Excitation for Band-Notched Ultra-Wideband Applications
By
Progress In Electromagnetics Research Letters, Vol. 15, 99-106, 2010
Abstract
In this paper, a novel band-notched wide slot antenna for UWB applications has been proposed. The antenna consists of a circularly slotted square ground, two wide-slots separated by a conductive ring, and an equiangular spiral feed line, which excites the antenna through traveling-wave. Experimental prototypes are fabricated and tested. The obtained results indicate that the proposed antenna has a small size and offers a broad bandwidth from 3.1 to 12 GHz, with a band notch from 3.4 to 3.9 GHz. The radiation patterns display nearly omnidirectional performance and the measured group delays are within ±1 nanosecond except for the notch band.
