| description | The development and improvement of operational characteristics of communication lines, radiolocation, navigation, surface overview, remote control and warning systems at the airports and at the stations is provided by the development of shorter-wave ranges. Designing new millimeter and submillimeter waveband radio complexes requires not only the modernization of existing antennas but also the creation of new antennas classes. Diffraction radiation antennas, for example. One of the basic problems in antenna engineering is the formation of required amplitude-phase distribution (APD) of electromagnetic field on antenna aperture that provides the given operational characteristics. The known techniques of APD forming at the aperture of diffraction radiation antennas are acceptable for aperture not less than 50 wavelengths. In this paper the possibility of forming the amplitude distribution with symmetrically falling edges at the 10...50 wavelength aperture by adding an additional segment of dielectric waveguide is investigated. The additional segment of dielectric waveguide changes the sequential system of radiating elements feeding into a sequential-parallel one. The efficiency of energy and APD transformation for different values of dielectric waveguide – dielectric waveguide and dielectric waveguide – grating coupling factor is evaluated. The results can be applied in the design of millimeter antenna systems and functional unit based on open transmission lines. |
