Abstract:
1. An antenna array system, comprising: a plurality of antenna elements organized in an array and configured to form a non-planar shaped antenna array surface, each of the plurality of antenna elements being switchable to one of a plurality of phase shift states; and phase-shift switching circuitry configured to switch one set of the antenna elements to one of the phase shift states and switch another set of the antenna elements to another of the phase shift states based on phase control signals for steering an antenna beam to a direction, the one set and another set being one and another of at least four sets of the antenna elements, a first set having a phase delay range of (−45°, +45°), a second set having a phase delay range of (+45°,+135°), a third set having a phase delay range of (+135°,+225°), and a fourth set having a phase delay range of (+225°,+315°).
