Electrodynamic model of the receiving antenna in terms of a waveguide representation of the HF field

This paper is concerned with the problem of current excitation in a receiving antenna in an HF field. The solution of the problem is performed in terms of a waveguide representation of the HF field in the spherical Earth-ionosphere waveguide. Structurally, the antenna is treated in the form of a conductor of a finite length and arbitrary configuration.
