Modeling the Characteristics of Antenna Based on the Flat Focusing Reflector

Abstract

The paper considers the problem associated with the construction of an antenna, based on the flat focusing reflector with waveguide slots of a square profile, filled with a homogeneous dielectric. Algorithms for antenna modeling and optimization are presented. Optimization is based on the use of a multi-criteria approach. The antenna directional diagram for the main frequency is demonstrated. Frequency dependences of antenna efficiency and aperture efficiency are shown. The illustration of the phase distribution that will correspond to the surface of the aperture for boundary frequencies is demonstrated. The illustration is given of the phase distribution at the emitting aperture at frequency for cutoff frequencies.
