Abstract

A broadband antenna for impulse radio ultrawide-band (IR-UWB) localization is evaluated to confirm its suitability. The introduced antenna consists of a circular patch with eight concentrically positioned shorting pins, which is fed by a quasi-cone probe at its center. The antenna has an impedance band-width of 44.1%, which is from 6 to 9.4 GHz. The system fidelity factor (SFF) and group delay of the antenna are calculated both in examinations and simulations. The SFF of the antenna under test is greater than 98% and the group delay remains stable throughout the frequency band, which validates its applicability for IR-UWB systems.
