Abstract
In accordance with various aspects of the present invention, a method and system for designing an inclined antenna array with a hybrid mechanical-electronic steering system with improved radiation performances at low elevation angles is presented. In an exemplary embodiment, a radiating element structure is attached to a mounting surface and includes a patch antenna and a ground plane. The bottom edge of the patch antenna is farther from the mounting surface than the top edge of the patch antenna. If the radiating element structure is used in an inclined array antenna, then the patch antenna has an uncovered view of a low elevation angle. Furthermore, at least a portion of a patch antenna may be uncovered and have a clear view. A clear view of the low elevation angle results in increased directivity and increased polarization quality due to reduced signal scattering.
