To aim at the ultra wideband fuze antenna bandwidth and the volume factor, modeling and simulation of the UWB antenna are studied with computer simulation technology. The UWB fuze antenna voltage standing-wave ratio and antenna gain are analyzed in the frequency domain, and the UWB antenna radiation characteristics of signals and antenna pattern are analyzed in the time domain. In comparison the time domain analysis method is more suitable for ultra wideband antenna. It is shown that for ultra wideband fuze antenna, priority should be given to the time domain method, with the frequency domain method as a supplement, in order to get an ideal simulation result.
