| Abstract: | In this paper, a radiator employing the Cherenkov mechanism for electromagnetic energy transfer from an optically less dense medium into a more dense one is developed and studied using a two-dimensional numerical model. The radiator's principal components are a dielectric prism and an open dielectric waveguide, where the phase velocity of waves exceeds that within the prism. For two linear polarizations in the 24 to 64 GHz range, and this radiator exhibits high efficiency (over 93%) and radiation patterns with main lobes that closely coincide in both direction and width. The direction of radiation demonstrates strong agreement with predictions from the Cherenkov wave theory and shows weak dependence on frequency. These characteristics make the developed antenna suitable for the directional emission and reception of electromagnetic pulses of various polarizations with spectral bandwidths of up to one octave or more. It is demonstrated that the radiation patterns of such antennas can be electrically controlled by altering the permittivity of the dielectric waveguide using an external control signal. The proposed antenna design avoids expensive fabrication processes and can be scaled to sub-millimeter wave ranges without significant modifications. [ABSTRACT FROM AUTHOR] |
