Popis: Characteristics of radiation of electromagnetic waves from flat metallic waveguide filled with a dielectric and having the finite number of not equidistant parallel slots on one side of the waveguide excited by a fundamental waveguide wave are studied. This structure allows an accurate electrodynamical solution with minimum known radiophysical assumptions and as a model might correspond to real antennas fabricated of thin foiled dielectric having electrically long slots. The problem is solved by the method of analytical semi-inversion of original problem operator combined with the method of moments. The near and far radiation fields (Е and Н-field components), as well as power characteristics of reflected and propagated in the waveguide fields are analyzed.
