Microwave slot antenna on dielectric resonators

Investigation results of the antenna, which represents a system of coupling cylindrical dielectric resonators (DRs), situated in apertures of the wide wall of the rectangular metal waveguide, are given. Every DR has the lowest magnetic resonance H_01delta, the combined system is a whole emitting structure that forms narrow radiation pattern. It is indicated that antennas of this sort alongside with sufficiently narrow directional diagram have wider transmission bands. Main electrical parameters such as antenna radiation pattern, S-matrix coefficients, coupled and forced resonance amplitudes were calculated.
