Abstract :
A novel circular wide slot ultra wideband antenna fed by coplanar waveguide is proposed and designed. This antenna has the characteristics of miniaturization and planarity which is operated at 3GHz~12GHz frequency band. The radiation pattern characteristic is improved by strip-line loaded in the circular wide slot. Results show that this antenna can realize ultra wideband impedance bandwidth characteristic, good radiation pattern bandwidth and gain flatness. Good agreement can be gotten between measurement and simulation results, and this antenna can satisfy ultra wideband communication system application.
