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.

摘要： The present invention relates to the technical field of mobile communication devices, and provides a multi-standard integrated antenna array. The multi-standard integrated antenna array comprises a reflection plate, at least three high-frequency arrays, and at least one low-frequency array; the high-frequency arrays and the low-frequency arrays are all mounted on the reflection plate, each low-frequency array comprises at least one cross-shaped low-frequency radiation unit; each high-frequency array comprises a plurality of high-frequency radiation units; each cross-shaped low-frequency radiation unit is embedded in the horizontal and vertical central axes of the high-frequency radiation units; and the projection of each cross-shaped low-frequency radiation unit on the reflection plate is located outside the projection of each high-frequency radiation unit on the reflection plate. The cross-shaped low-frequency radiation unit is arranged on the horizontal and vertical central axes of each high-frequency radiation unit, such that the width of an antenna is decreased; and the projection of the cross-shaped low-frequency radiation unit on the reflection plate is located outside the projection of the high-frequency radiation unit on the reflection plate, such that the coupling between the high-frequency arrays and the low-frequency arrays is reduced, and the performance of the antenna is optimized.
