A wide-angle mechanoelectrical steering antenna system based on multilayer dielectric wedge structure

The work presents the study of multilayer structure based on flat dielectric wedges which provides linear phase shift for wide-angle beam steering antennas. The results of numerical simulation are given including the radiation patterns of deflecting structure and of the whole antenna system based on it. Also some methods for improving the performance of the examined system were studied. The presented antenna system showed the ability of mechanoelectrical beam steering within the range of ±45° in elevation plane and 360° in azimuthal plane. The directivity deterioration in elevation plane reached 3 dB relative to zero direction.
