Electromagnetic Wave Radiation from Flat Waveguide with Finite Number of Slots

Characteristics of the radiation of electromagnetic waves from the flat metallic waveguide filled with a dielectric and having the finite number of non-uniform parallel slots placed on one side of the waveguide excited by a fundamental waveguide wave are studied. This structure allows an accurate electrodynamic solution with minimum familiar radiophysical assumptions and as a model might give good correspondence 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 in combination with the method of moments. Near and far radiation fields (E and H-field components), and power characteristics of reflected and propagated in the waveguide fields are analyzed also.
