Abstract

This paper presents a novel wide beam UWB antennae design for Impulse Radio-Ultra Wide Band (IR-UWB) Through-the-Wall detection radar. The design is based on a typical bowtie slot antenna structure with an added reflector in order to achieve unidirectionality and wide beam. The effects of different parameters of the added reflector on the impedance and radiation characteristics are analyzed. The different structural parameters of antenna are optimized by numerical simulations. Simulated and measured results show that the front-to-back ratio is great than 10 dB and the beam width is approximately 120° ~145° within operation band for |S11|<;-10dB (0.8GHz~2.3GHz).
