摘要： RF signal transmission devices for a base station antenna include a printed circuit board which has a dielectric layer, a metal pattern layer on a first main surface of the dielectric layer, and a ground layer on a second main surface of the dielectric layer. The metal pattern layer has a transmission line deformation section for enhancing the ability to withstand surge current, and the ground layer comprises a groove that is configured to at least partially compensate for the change in the characteristic impedance due to the transmission line deformation section. The RF signal transmission device can achieve good characteristic impedance matching whilst enhancing the capacity to withstand surge current. In addition, the RF signal transmission device can improve PIM performance. The present disclosure also includes a phase shifter for a base station antenna and a base station antenna.

摘要： The present application relates to a mounting device configured for mounting a base station antenna (10) on a supporting member (11), and providing the adjustability of the mechanical tilt angle of the base station antenna. The mounting device comprises a first mounting unit, a second mounting unit, and an elastic element (3). The first mounting unit is configured to provide a pivot point for the base station antenna, the second mounting unit has an adjustable effective connection length for the base station antenna, with the effective connection length related to the mechanical tilt angle of the base station antenna, and the elastic element is configured to resist an increase in the mechanical tilt angle of the base station antenna on at least a part of the adjustable range of the mechanical tilt angle of the base station antenna. The mounting device allows for the easy adjustment of the mechanical tilt angle of the base station antenna, reducing the workload and safety risks of the operator.
