    摘要: Base station antennas include a RET actuator, a plurality of phase shifters and a plurality of mechanical linkages, where each mechanical linkage is connected between the RET actuator and a respective one or more of the phase shifters. The RET actuator includes a rotary drive element movable in a first rotary direction and a second rotary direction. A first drive system is connected between the rotary drive element and the first mechanical linkage. The first drive system moves the first mechanical linkage in a first linear direction and a second linear direction when the rotary drive element is moved in the first rotary direction. A second drive system connected between the rotary drive element and the second mechanical linkage. The second drive system moves the second mechanical linkage in a third linear direction and a fourth linear direction when the rotary drive element is moved in the second rotary direction.

    摘要: Methods and systems for a steerable antenna array are disclosed. The antenna array includes an array of antenna elements aligned in rows and columns on a substrate. Additionally, the antenna array includes a microstrip feed within the substrate, where the feed is configured to electromagnetically couple to each antenna element of the array of antenna elements. The antenna array further includes a ground plane within the substrate. Additionally, for each antenna element, the antenna array includes a first cavity disposed between the ground plane and feed, and a second cavity disposed on the other side of the ground plane from the first cavity. The antenna array further includes a plurality of fluid lines configured to selectively add or remove fluid from the cavities coupled to the fluid line and cause a deflection of the ground plane in a region of the cavities coupled to the fluid line.

    摘要: The present disclosure relates to a phase shifter, which includes: a phase shift circuit board with conductive traces printed thereon; and a phase shift circuit board with conductive traces printed thereon; and a slide device with a first tooth section configured to be driven, wherein movement of the first tooth section drives the slide device to slide on the phase shift circuit board. In addition, the present disclosure further relates to a remote electrical tilt system, which includes an actuator, a transmission mechanism, and at least one phase shifter according to the present disclosure, wherein the actuator is configured to drive the transmission mechanism, and the transmission mechanism engages the first tooth section to drive the slide device to slide on the phase shift circuit board. In addition, the present disclosure also relates to a base station antenna which includes the remote electrical tilt system according to the present disclosure. The base station antenna according to the present disclosure may improve the stability of the transmission of the remote electrical tilt system and increase the space utilization of the remote electrical tilt system.
