本文提出了用于移动 Ka 波段卫星通信的折叠反射阵列的两个双偏振反射阵列单元和用于直接辐射阵列的线性偏振阵列单元。所有这些天线单元均具有多层结构，专为波束可转向大扫描角度的智能阵列天线而设计。反射阵列的单元设计为在 29.5-30.8GHz 频段运行，用于发射和接收，而直接辐射阵列的天线元件设计为双频段运行：29.5-30.8GHz 用于发射，19.7-21.0GHz 用于接收。这三个天线元件外形较小，仿真结果表明它们在所需频段上表现出良好的辐射性能。
Two dual-polarised reflectarray unit cells for the folded reflectarray and one linearly polarized array element for direct radiating array for Ka-band SatCom on the move are presented in this paper. All of these antenna unit cells have multi-layered structure and are designed for the smart array antenna with beams that can be steered to large scanning angles. The unit cells for reflectarray are designed to operate at 29.5-30.8GHz band for both transmitting and receiving while the antenna element for the direct radiating array is designed to have a dual band operation: 29.5-30.8GHz for transmitting and 19.7-21.0GHz for receiving. These three antenna elements have a low profile and the simulation results show that they exhibit good radiation performance over the required frequency bands.
