Abstract: A base station antenna includes an internal radome and a multi-column antenna array antenna. The internal radome can be configured with a plurality of columns, each having an outwardly projecting peak segment and each neighboring column of the internal radome can be separated by a valley. Each outwardly projecting peak segment(s) is oriented to project toward a front of the base station antenna and is positioned medially aligned over a respective column of the multi-column antenna array to thereby reduce mutual coupling of respective elements and/or columns of elements and/or provide a common near field environment for each element and/or each column.

Abstract: The present invention provides a phase shifter assembly for an array antenna, comprising: a first level phase shifter, wherein the first level phase shifter is configured to control the phases of a plurality of sub-arrays of the array antenna, where each sub-array comprises one or more radiating elements; a second level phase shifter, wherein the second level phase shifter is configured to proportionally change the phases of the radiating elements in the corresponding sub-arrays; and a power divider, wherein the power divider is connected between the first level phase shifter and the second level phase shifter. The phase shifter assembly has the advantages of both a distributed phase shifter network and a lumped phase shifter network. Specifically, the phase shifter assemblies can independently control the phases of the radiating elements in the array to obtain better sidelobe suppression. Further, phase control parts of the phase shifter are concentrated within a certain physical space range, so the size of the phase shifter assembly may be greatly decreased, and the cost may be greatly reduced, as compared with a conventional distributed phase shifter assembly design.
Abstract translation: 本发明提供了一种用于阵列天线的移相器组件，包括：第一电平移相器，其中第一电平移相器被配置为控制阵列天线的多个子阵列的相位，其中每个子阵列 包括一个或多个辐射元件; 第二电平移相器，其中所述第二电平移相器被配置成按比例地改变相应子阵列中的辐射元件的相位; 和功率分配器，其中所述功率分配器连接在所述第一电平移相器和所述第二电平移相器之间。 移相器组件具有分布式移相器网络和集总移相器网络的优点。 具体地，移相器组件可以独立地控制阵列中的辐射元件的相位以获得更好的旁瓣抑制。 此外，移相器的相位控制部分集中在一定的物理空间范围内，因此与传统的分布式移相器组件设计相比，可以大大降低移相器组件的尺寸，并且可以大大降低成本。
