Abstract
The design of ultra-wideband antipodal Vivaldi antenna with parasitic patch is presented. The different shapes of parasitic patch i.e., elliptical shape, diamond shape, stepped shape which are placed on antenna aperture are proposed. The effect of these parasitic patches on reflection coefficient, gain, radiation pattern, front-to-back ratio and electric field distribution is discussed. The simulation results show that all parasitic patches can operate in frequency range from 3.1 to 10.6 GHz for UWB applications. Moreover, using these parasitic patches, the gain, radiation patterns, front-to-back ratio and electric field distribution are improved.
