Abstract
This article presents the results of research of dependence of parameters of the antenna array, collected from the Vivaldi antenna radiators, depending on the changing of distance between the radiators. Shows the stage of modeling the antipodal Vivaldi antenna in the circuit simulation program High Frequency Structure Simulator. Shows the main characteristics for that antenna. Shows a simulation of the antenna array, consisting of the resulting Vivaldi antenna. Shows the main characteristics for it: voltage standing wave ratio, radiation pattern, input impedance. Carried out the comparative analysis of the obtained characteristics, whereby selected the optimal distance for location of antenna radiators.
