  • The finite difference time-domain method is used to analyse the wide-hand impedance characteristics in UHF band of the tapered slot antenna in this paper. And the SWR of a, Vivaldi antenna is calculated, is in good agreement with the experimental results. The results show that the methods of modeling in this paper are correct and valid. The antenna SWR, changes a little within two octaves, so this antenna can work in wide-baud held.
