An antenna for radiating and receiving short-pulse ultra-wideband signals

Abstract

This paper presents a design of the antenna with an expandable slot for effective radiating and receiving the ultra-wideband (UWB), short-pulse signals. The offered design of the antenna allows creating an interferential electromagnetic field of a bipolar pulse in an equivalent general antenna aperture. A quantitative and quality evaluation of efficiency of proposed antenna design is performed. It is shown that an application of the given antenna allows increasing the propagation range of the pulsed UWB signals.
