【 摘 要 】

The paper analyzes the directional properties of antipodal of Vivaldi antenna, located on the faces of the wedge, coupled with the two cylinders at the top and bottom. Two antenna patterns are considered. The first pattern has one antenna, located symmetrically on the edge of each face of the wedge, the second pattern has two of them. The comparative analysis of these antennas is done. The influence of the angle at the apex of the wedge and its size on the parameters of antennas is studied. The frequency and directional characteristics of antennas depending on their structural dimensions and their location are examined.
