Abstract: A multi-antenna mounting device includes: a mounting member to which two or more antennas are fixable; and a tilt angle adjusting mechanism including an upper adjusting component and a lower adjusting component spaced apart along a length direction of the mounting member. The upper adjusting component includes a plurality of tilt angle adjusting holes arranged in a row, one end of the upper adjusting component is connectable to the mounting member, and the other end is connectable to a user's support pole with a fastening element extending through one of the tilt angle adjusting holes. When the fastening element extends through different tilt angle adjusting holes, the multi-antenna assembly has different mechanical tilt angles relative to the support pole. The lower adjusting component includes a first section and a second section. The second section has a predetermined length and the first section is pivotable relative to the second section.

Abstract: The present disclosure relates to a mechanical transmission mechanism and a base station antenna. The mechanical transmission mechanism extends between an actuator and a phase shifter of the base station antenna, and comprises: a first rod driven by the actuator; a second rod for moving a movable element of the phase shifter, the second rod having a proximal end and a distal end; and a link for connecting the first rod and the second rod, the link having a proximal end and a distal end and including a first connecting element that movably connects the first rod with the link and a second connecting element that fixedly connects the second rod with the link; wherein position of the distal end of the second rod relative to the proximal end of the link is adjustable, so that a length of the second rod extending from the proximal end of the link is adjustable, thereby eliminating a virtual displacement caused by mechanical tolerances from the actuator, the mechanical transmission mechanism, and the phase shifter during adjustment of the phase shifter.

Abstract: The present disclosure relates to a transmission mechanism for a base station antenna, including: a motor having an output shaft; a gear assembly including a first gear and a second gear meshed with each other, an output end of the output shaft connected to the first gear and driving the first gear to rotate; a screw, a first end thereof connected to the second gear and a second end thereof rotatably supported by a support element; a movable element mounted on the screw, fixedly connected to one end of a connecting rod and translating along an axial direction of the screw when the screw rotates, thereby driving the connecting rod to translate along the axial direction; and an anti-rotation element configured to cooperate with the movable element to prevent the movable element from rotating with the screw, where the motor and the screw are configured to be arranged parallel to each other on a same side of the gear assembly. The transmission mechanism of the present disclosure can have a smaller length, can provide greater axial force to the connecting rod, and/or can be assembled and disassembled more quickly.

Abstract: A transmission device for a base station antenna includes a motor, a screw driven by the motor, a transmission shaft, and a linkage system. The linkage system is connected with the screw via the transmission shaft, so that the screw drives the linkage system via the transmission shaft. The linkage system includes: a worm driven by the transmission shaft, a worm gear meshed with the worm, at least one spur gear disposed on a same connecting shaft as the worm gear, and at least one connecting rod engagement element. The spur gear and the worm gear are fixed relative to each other. The connecting rod engagement element has a rack meshed with the spur gear, so that the worm drives the worm gear to rotate with the spur gear, and the spur gear drives the connecting rod engagement element via the rack to move in an axial direction of the transmission shaft.

Abstract: Printed circuit boards for a base station antenna include a substrate layer, and a first conductive trace and a second conductive trace which are printed on the substrate layer and cross each other. The first conductive trace has two trace sections separated by the second conductive trace. Adjacent ends of the two trace sections separated by the second conductive trace are connected electrically by a jumper. The jumper has an electrical conductor, is isolated electrically from the second conductive trace and is fixed on the printed circuit board. The electrical conductor and the two trace sections are connected electrically at adjacent ends. The printed circuit board allows flexible wiring of the conductive traces on the printed circuit board.
