Study on the Characteristics of A Compact Ultra Wideband Antenna
A new kind of Ultra Wideband (UWB) antenna, which consists of a leaf-like dipole and a dielectric block, is proposed and analyzed. The dielectric block is parallelly attached to the feed point of the leaf-like dipole, so the near field can be attracted to the side where dielectric block located, this leads to a focusing effect of the energy in the far zone. The leaf-like dipole itself is a wideband antenna, with proper resistance loading on the leaf-like elements, the impedance bandwidth of the antenna defined by VSWR less than 2.3 achieves 6.9 GHz (from 3.1GHz to 10 GHz), which satisfies the UWB requirement given by FCC. The characteristic impedance of the feeding cable is 50 ¿.
