Multielement systems of double slots in rectangular waveguide with partial dielectric filling

Abstract

Resonance characteristics of narrow transversal slots, energetic and directional characteristics of an antenna array (AA) with single transversal slots and double ones cut in a rectangular waveguide, partially filled with dielectric are investigated. In the case of the single transversal slots and double transversal slots a dielectric layer is parallel to broad walls of the waveguide. It was shown the possibility to construct an AA with double transversal slots the pattern without diffraction lobes and high level of radiation power in the frequency band.
