摘要：
支持地球静止轨道（GEO）卫星多播业务的高性价比、低剖面卫星通信用户终端需求日益增长，已成为众多要求下行链路高数据速率的直播到户（DTH）服务商的核心关注重点。采用超表面提升频率带宽与性能比的平面天线阵列被视为此类系统的有效解决方案。本文提出一种低成本、孔径耦合的超表面增强型贴片天线，工作在10.7-12.7 GHz频率范围内。该天线采用矩形晶格排布的32×32阵列结构，设计目标为在目标频段内实现至少27 dBi的实际增益。天线初始配置为线极化，可根据需求升级支持双极化或圆极化。
英文摘要：
The demand for cost-effective, low-profile user terminals for satellite communications supporting multicast services for Geostationary Orbit (GEO) satellites, has become a key focus for many Direct-to-Home (DTH) providers where the high data rates in the downlink are required. Planar antenna arrays with increased frequency bandwidth and improved ratio using meta-surfaces are considered as an effective solution for such systems. This paper presents a low-cost, aperture-coupled metasurface-enhanced patch antenna, operating within the 10.7-12.7 GHz frequency range. The antenna is designed to achieve a realized gain of at least 27 dBi across the band of interest using 32 x 32 array antennas distributed in a rectangular lattice. Initially configured for linear polarization, the antenna can be upgraded to support dual or circular polarization if required.
