    • 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.
    • 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。

    • A multi-band radiating array includes a planar reflector, first radiating elements defining a first column on the planar reflector, second radiating elements defining a second column on the planar reflector alongside the first column, and third radiating elements interspersed between the second radiating elements in the second column. The first radiating elements have a first operating frequency range, the second radiating elements have a second operating frequency range that is lower than the first operating frequency range, and the third radiating elements have a third, narrowband operating frequency range that is higher than the second operating frequency range but lower than the first operating frequency range. Respective capacitors are coupled between elongated arm segments and an elongated stalk of the third radiating elements, and a common mode resonance of the third radiating elements is present in a lower frequency range than the second operating frequency range,

    • The present invention relates to a cavity phase shifter with a housing having at least one cavity and a transmission line mounted in the cavity. The transmission line is provided with an input end and an output end. The output end of the transmission line is electrically connected to another transmission line outside the cavity without the aid of a cable. The cavity phase shifter also includes a movable element mounted within the cavity. Movement of the movable element is configured to adjust a phase shift experienced by an RF signal that travels between the input end and output end of the transmission line. The cavity phase shifter can be provided in a base station antenna having a reflector; a feed board mounted forwardly of the reflector; and a radiating element extending forwardly from the feed board. The phase shifter is mounted rearward of the reflector. The phase shifter includes a printed circuit board that extends perpendicularly to the feed board, and an output end of a transmission line on the printed circuit board is soldered to a trace on the feed board. Thus, the insertion loss associated with the phase cables would be reduced and the gain performance of the antenna can be improved.
