Characteristics of Vivaldi antennas in the radiation and scattering mode

To expand the radiation pattern in the plane of the magnetic field vector, it is proposed to make a design from the classical antenna in the form of a fan of such antennas with a common array feed point. A comparative analysis of the directional and scattering characteristics of single and fan antenna Vivaldi was carried out. The efficiency of their use as reflectors of electromagnetic properties is estimated.
