Article Preview

The Vivaldi antennas are widely used in many wide band electronic systems for its good performances. This paper designed and simulated two kinds of Vivaldi antennas for wide band passive radar applications, which are the antipodal Vivaldi antenna fed by strip line and antipodal Vivaldi antenna fed by microstrip line. The specific design parameters and the radiation performances of each kind of vivaldi antenna are provided over the operating frequency range of 3GHz to 11GHz. Furthermore a circular antenna array with six Vivaldi antenna elements fed by microstrip lines was also simulated to obtain its radiation performances over the operating frequency range of 3GHz to 8GHz. The simulation results demonstrate the designed Vivaldi antennas have acceptable performances of voltage standing wave ratio (VSWR), patterns and gains, so they can be used in practical wide band radars.
