摘要： 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.

摘要： In an exemplary embodiment, a modular phased array comprises a ground plane with a first side and a second side, where the ground plane has a slot. The modular phased array also comprises a patch antenna located on the first side of the ground plane, and a feed network located on the second side of the ground plane. In an exemplary embodiment, the ground plane isolates the patch antenna from the feed network. The feed network includes a compacted hybrid with two output ports. In an exemplary embodiment, the ground plane comprises slots that are nonorthogonal and nonparallel to the two output ports of the feed network. In another exemplary embodiment, the distance from the center of the patch antenna to the farthest output port of the two output ports of the compacted hybrid is ½ wavelengths or less.

摘要： A system and method of minimizing a polarization quantization error associated with an antenna sub-array. The antenna sub-array includes at least two radiating elements, with the radiating elements having different polarization orientations from other radiating elements in the antenna sub-array. The radiating elements are dual polarized and have electronic polarization control. In an exemplary embodiment, the radiating elements are configured to reduce the polarization quantization error to be less than half of a polarization quantization step size. In various embodiments, rotating the radiating elements and implementing a phase delay, individually or in combination, is used to change the polarizations of the radiating elements.
