摘要

空天地一体化建设是6G通信技术发展的关键，针对复杂的星地互连应用场景，提出了一种超宽角扫描全极化相控阵天线和相应的波束合成方法。天线单元包含可独立激励的四个辐射通道，可实现四种具有不同极化和覆盖范围的波束，并结合所提出的全极化波束重构方法，调整单元内四个通道的馈电功率权值和相位差，能够实现灵活的单元方向图与极化调控，满足接近半球空域的超宽角扫描全极化覆盖。将该单元应用于相控阵中，可进而实现具有全极化合成能力的超宽角波束扫描。设计、加工并实验验证了四单元线性阵列样机。测试结果表明该阵列的工作频段为2.35 GHz至2.45 GHz，阵元间各端口的隔离度优于15 dB，可以实现双线极化和圆极化接近±90°的超宽角波束扫描，最大扫描损耗仅3.9 dB。出色的多极化特性和低损耗的超宽角扫描能力可有效提升星地互连的质量和稳定性，进一步推动构建空天地一体化网络的建设。

Abstract

The development of space–air–ground networks is critical for 6G communications. An ultra-wide-angle scanning full-polarization phased array antenna with corresponding beam synthesis method was proposed for application in complex satellite–terrestrial interconnection scenarios. The full-polarization element contained four independent channels with different polarizations and beam ranges. The flexibility of element beamforming in beam direction and polarization was realized by adjusting the feeding power weight and phase difference of the four channels. The full-polarization ultra-wide-angle scanning was realized by applying the element in phased array. A four-element linear array prototype was designed

fabricated and experimentally verified in the band from 2.35 to 2.45 GHz. The isolation between each port were better than 15 dB. The beam scanning of

= ±90º for both linear polarization and circular polarization were achieved with low scan loss better than 3.9 dB. The excellent multi-polarization characteristics and low-loss ultra-wide-angle scanning capability can effectively enhance the quality and stability of satellite–terrestrial interconnections

thereby further promoting the development of space–air–ground integrated networks.
