Abstract: 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.

Abstract: The present disclosure relates to an antenna mounting device for antenna assembly, where the antenna assembly (20) comprises a base station antenna (21) that extends longitudinally and a remote radio unit (22). The antenna mounting device comprises a first mounting unit (1), a second mounting unit (2) and an optional third mounting unit (3). The first mounting unit is configured to pivotally connect a remote radio unit to a foundational component (23) and provide the antenna assembly with a pivot point (4) relative to the foundational component. The second mounting unit is configured to connect the base station antenna to a foundational component in the longitudinal extension direction of the base station antenna, below the first mounting unit and at a distance from the first mounting unit. The second mounting unit has an adjustable effective connection length between the base station antenna and foundational component, where the effective connection length determines the mechanical tilt angle of the antenna assembly. The present disclosure further comprises an antenna system of the antenna mounting device.

Abstract: The present disclosure relates to a transmission mechanism for a base station antenna, and a base station antenna including the transmission mechanism. The transmission mechanism includes a motor and at least one connecting rod, wherein a gear mechanism is provided on a first end of the connecting rod, and the motor drives the connecting rod to rotate via the gear mechanism; and wherein a worm gear unit is provided on a second end of the connecting rod opposite to the first end, and the worm gear unit is configured to drive a movable element of a phase shifter when the connecting rod rotates. The transmission mechanism according to the present disclosure can generate greater driving force through the worm gear unit, and has a shorter axial length and a smaller height, and thus is particularly suitable for a more compact and thinner 5G base station antenna.
