Abstract. In this work, a real design of a microwave horn antenna system is proposed and developed. Electrodynamic modeling of this system was carried out and the main electrical and design parameters of the proposed antenna system were determined. The radiation patterns of this antenna system were constructed in the vertical and horizontal planes. Mathematical models of the critical frequencies of the waveguide for the two highest types of electromagnetic waves are obtained. Mathematical models of the design of the proposed antenna system were also obtained. A power supply device for the emitting aperture has been developed. As the analysis results show, the antenna effectively radiates in the range of 40-60 GHz. The conditions for choosing a junction design are determined depending on the bandwidth and dimensions of the substrate. Based on electromagnetic modeling of a unit cell for a perforated dielectric lens, the dependence of the effective dielectric constant on the diameter of the through hole has been established. |
