Abstract: A cable includes a first part and a second part. The first part includes a cable core, a metal layer, and a dielectric layer. The metal layer wraps the cable core, and the dielectric layer is sandwiched between the cable core and the metal layer. The second part includes a plurality of metal units and a dielectric unit. The plurality of metal units are spacedly disposed on the metal layer of the cable, to reduce cable's shielding on an electromagnetic wave in a specific frequency band. The cable is placed on a radiation path of an antenna. This can reduce shielding on an electromagnetic wave radiated by the antenna, to avoid distortion of an antenna pattern.

Abstract: This application relates to the field of antenna technologies, and in particular, to an antenna assembly. The antenna assembly includes a first antenna array element, a second antenna array element, and a filtering structure. The first antenna array element supports receiving in a first frequency band, and the second antenna array element supports transmitting in a second frequency band. The filtering structure includes at least one of a first filtering structure and a second filtering structure. The first filtering structure is disposed on the first antenna array element, and the second filtering structure is disposed on the second antenna array element. Isolation of the antenna assembly is high.

Abstract: This application provides a downlink transmitting system and a switching method. The downlink transmitting system includes at least one digital intermediate frequency module group, at least one Tx port group, a plurality of PAs, at least one switching switch, and an antenna array. The plurality of PAs are connected to the antenna array. The plurality of PAs are connected to all Tx ports included in the downlink transmitting system in a one-to-one correspondence. The at least one digital intermediate frequency module group is in a one-to-one correspondence with the at least one Tx port group. Each Tx port group is connected to each digital intermediate frequency module in a corresponding digital intermediate frequency module group through one switching switch. Each Tx port group includes a plurality of Tx ports.

Abstract: An antenna array, including at least two antenna bays. Operating frequency bands of all of the at least two antenna bays are the same, each antenna bay includes at least one transmit channel or receive channel, and each antenna bay transmits data in a co-frequency co-time full duplex manner. Alternatively, operating frequency bands of two adjacent antenna bays of the at least two antenna bays are adjacent frequency bands or are separated by one or two frequency bands, each antenna bay includes at least one receive channel and at least one transmit channel, and each antenna bay transmits data in an asynchronous manner. An angle value between a line connecting center points of any two adjacent antenna bays of the at least two antenna bays and a horizontal line is acute. By using the present invention, isolation between antenna bays of the antenna array is increased.
