    摘要: A transmission switching device, comprising a linear transmission member (1), a transmission shaft (2), a transmission assembly (3), and a switching output assembly (4). The transmission assembly comprises a support (31) and a driving gear (32), the driving gear and the transmission shaft being both rotatably mounted on the support. The transmission shaft is coaxially connected to the driving gear and is used for driving the driving gear to rotate. The linear transmission member is connected to the support and is used for driving the support to reciprocate. The switching output assembly comprises a plurality of switching output shafts (41), each switching output shaft being provided with a switching output gear (42). The driving gear can be in driving connection with the plurality of switching output gears. The transmission switching device may switch and output to different phase shifters power input into the transmission assembly, so that the phase shifters are driven by fewer driving members, and thus the number of the driving members is reduced. Further provided are a driving device comprising said transmission switching device, and a base station antenna.

    摘要: The present application provides a switchable beam phase shifter and an antenna. The switchable beam phase shifter comprises an arc conductor assembly and a coupling assembly. The coupling assembly rotates about the center of the arc conductor assembly, and the arc conductor assembly comprises a first arc conductor and a second arc conductor. The first arc conductor and the second arc conductor are arranged in a circle around the center of the circle, one of the first arc conductor and the second arc conductor is a slow wave structure, and two ends of the first arc conductor and two ends of the second arc conductor are each provided with an output port. When the coupling assembly is located at a first position, the coupling assembly is coupled and electrically connected to the first arc conductor, and when the coupling assembly is located at a second position, the coupling assembly is coupled and electrically connected to the second arc conductor. The switchable beam phase shifter provided by the present application may switch between the two working states of a wide beam and a narrow beam by means of the coupling connection between the coupling assembly and different arc conductors, and has good impedance matching and relatively high practicality.

    摘要: The present application provides a radiation unit and a base station, and relates to the technical field of communications. The radiation unit comprises a substrate and two groups of radiation arms. Each group of radiation arms comprises two radiation single arms. Each radiation single arm has at least one decoupling structure. Two radiation single arms of the same group of radiation arms are coupled by means of a radiation surface. One radiation single arm in each group of radiation arms is located on a first surface of the substrate, and the other radiation single arm is located on a second surface of the substrate; or, the two radiation single arms in each group of radiation arms are located on the same surface of the substrate. In the radiation unit and the base station antenna provided in the present application, the two radiation single arms of each group of radiation arms are disposed on two surfaces of the substrate, respectively, thereby increasing the impedance bandwidth. By coupling the two radiation single arms in the same group of radiation arms by means of the radiation surface and adjusting the coupling area, the attenuation of inter-frequency signals is achieved, the decoupling effect is enhanced, and the technical problem in the existing technology that mutual coupling between frequency bands is difficult to reduce in a fused array antenna is resolved.
