Electrodynamic characteristics of multielement coaxial-slot antenna

The electrodynamic characteristics of coaxial-slot systems are calculated by the magnetomotive forces method (MMF) taking into account the internal and external space interconnections between the radiators on conditions of arbitrary location of the slot elements when internal and external spaces were filled with the dielectric for any values of permittivity. The problem of influence of interconnections between the radiators on the excitation and radiation of the array of narrow circumferential or arc transverse slots cut in the infinitely thin and perfectly conducting coaxial line screen was solved in this paper. The results of calculation and analysis of the amplitude and phase distributions in the slot arrays, directional and energy antenna characteristics depending on the working wavelength in cases of the slot element location on the infinite coaxial lines have been proposed. These results were compared with the results of the calculation without mutual interconnections.
