Abstract:
A problem of electromagnetic wave diffraction by a longitudinal slot cut in a waveguide wide wall is solved by a generalized method of induced electro-magneto-motive forces (EMMF). The slot radiates in a half-space above a perfectly conducting plane where two vertical impedance monopoles are arbitrarily located. To control electrodynamic characteristics of the radiator, a passive impedance monopole is placed in the waveguide. The paper is aimed at the study of the electrodynamic characteristics of waveguide vibrator-slot structures, analogous to the known Clavin element, with two identical impedance monopoles on both sides of the narrow half-wave slot. The influence of the geometric structure parameters on the directional characteristic of Clavin type element: relative level of sidelobes in the E-plane and the RP width differences in the main polarization plane at 3 dB level was analyzed. It was shown that the directional and energy characteristics of the radiators: radiation and reflection coefficients, antenna directivity, and gain can be varied within wide limits by changing the electrical length and/or distributed surface impedance of the vibrators.
