Abstract

The method of induced magnetomotive forces is used for solving the problem of distribution of equivalent magnetic currents in an antenna-waveguide structure of the “two-slot resonant diaphragm—rectangular resonator—radiating slot” type on the end face of a semi-infinite rectangular waveguide. The numerical and experimental investigations of this system are performed and the plotted electrodynamic characteristics are presented.
