A study of a leaf-shaped bowtie slot antenna for UWB applications

Ultra-wideband (UWB) radio technology has recently attracted considerable attention for various applications, such as short-range high-speed communication, sensor networks, radar and location tracking. The Federal Communications Commission (FCC) announced its decision to allow the unlicensed use of the frequency band from 3.1GHz to 10.6 GHz for UWB radio systems in 2002. Since then, many research groups have reported various kinds of UWB antennas. In particular, planar-type UWB antennas have attracted significant research power in the past few years. For example, Schantz proposed various new designs such as magnetic slot antennas [1] and planar elliptical dipole antennas [2]. Chen et al. investigated the characteristics of a few types of square dipole antennas [3] and also proposed the bi-arm rolled monopole [4].
