摘要：
A novel onmi-directional ultrawideband (UWB) monopole antenna is described. In the first part, the monopole antenna which is in the shape of an eye placed above a flat ground plane is designed and fabricated. This antenna operates from 3-20 GHz with low voltage standing wave ratio (VSWR) (<1.5). To keep the main radiating beam fixed over the frequency range of interest without degrading the VSWR, ground plane shaping will be introduced leading to an antenna that operates from 3-20 GHz with low VSWR (<1.8). This eye antenna is fed by a coaxial probe through a SMA connector. The length of the proposed monopole element above the ground is slightly less than lambda/4 of the lowest frequency in the band. Simulation and test results for VSWR, gain and radiation pattern of both antennas are presented and discussed.
