Abstract: A transmission line assembly includes a shielding cover and a signal line. The shielding cover is connected to a ground end. The shielding cover has an accommodation space. A first opening and a second opening are provided in the accommodation space. The signal line includes a first end and a second end that are disposed opposite to each other. The signal line penetrates the accommodation space, and there is a gap between the signal line and an inner side wall of the accommodation space. The first end passes through the first opening. The second end passes through the second opening. At least one of the first end and the second end of the signal line is configured to be connected to a signal end. The signal line is in an air dielectric, so that a signal loss is effectively reduced.

Abstract: This application discloses an antenna, an antenna array, and a communications device. The antenna includes a radiation part and a feeding part. The feeding part is coupled to the radiation part and is configured to feed power to the radiation part, so that the radiation part radiates a low-frequency signal outward. The radiation part includes one or more frequency selection units with a bandpass characteristic, and the radiation part is a structure that is capable of exciting, when a high-frequency signal passes through, coupling currents. When the high-frequency signal passes through the radiation part, each pair of coupling currents excited on the radiation part appear in pairs and can cancel each other. This can reduce or even completely eliminate a high-frequency induced current with the same frequency as the high-frequency signal on the radiation part.

Abstract: This application relate to the field of communications technologies, and disclose a backup power supply control method, to obtain target power supplying duration of a battery, and determine average power consumption of a communication station (101) within a time period corresponding to the target power supplying duration. Further, a state of charge of the battery is obtained, and actual power supplying duration for the battery to supply power to the communication station (101) is determined based on the state of charge of the battery and the average power consumption. Therefore, an operation mode of a communication device in the communication station (101) may be adjusted, to reduce the average power consumption of the communication station (101) within the time period corresponding to the target power supplying duration.
