极化可重构的相控阵天线和通讯装置
By stacking the power divider layer, liquid crystal phase shifter, and radiator layer along the first direction in the phased array antenna, and placing the liquid crystal phase shifter vertically, the problem of excessively large radiating element area caused by the side-by-side arrangement of the liquid crystal phase shifter and radiator is solved. This achieves a radiating element spacing of less than half the operating wavelength, improving antenna performance and integration, and reducing system complexity and cost.

AI Technical Summary
In existing phased array antennas, the side-by-side arrangement of liquid crystal phase shifters and radiators results in a large radiating element area, making it difficult to meet the requirement that the element spacing is no more than half of the operating wavelength, thus affecting antenna performance and increasing system complexity.
A power divider layer, a liquid crystal phase shifter, and a radiator layer are stacked along a first direction. The liquid crystal phase shifter is placed vertically to form a polarization-reconfigurable radiating unit. Polarization reconfiguration and beam pointing control are achieved through phase adjustment of the liquid crystal phase shifter, thereby reducing the area of the radiating unit.
It significantly reduces the area of the radiating element, prevents grating lobes, improves antenna performance, reduces system complexity and cost, enhances integration and power efficiency, adapts to various polarization scenarios, and has the advantages of fast scanning speed and high efficiency.
