Abstract: This application discloses a power supply management system, and a power supply management method and apparatus applied to the system. The system includes a power sourcing equipment, a powered device, and a power supply line. The power sourcing equipment sends a second voltage to the powered device to determine a first voltage. The first voltage is a maximum power supply voltage agreed on by the power sourcing equipment and the powered device. The power sourcing equipment supplies power to the powered device based on the first voltage. In this application, the power sourcing equipment supplies power to the powered device based on the maximum power supply voltage that can be supported by the powered device, so that a loss on the power supply line is reduced.

Abstract: An antenna subarray and a base station antenna are disclosed. The antenna subarray includes a reflection plate, a plurality of radiation surfaces, and a ground plate of the plurality of radiation surfaces. The ground plate is vertically disposed on the reflection plate, and includes an integrated bottom end structure and a plurality of branch structures. The bottom end structure is connected to the reflection plate, and a top end of a branch structure is connected to a radiation surface. A feeder layer is disposed on a side of the ground plate, and a dielectric layer is spaced between the ground plate and the feeder layer. A first polarized feeder and a second polarized feeder are disposed on the feeder layer. The ground plate may have both a “ground” function of a polarized feeder and a “ground” function of a balun. The first polarized feeder and the second polarized feeder can implement both a function of a polarized feeder of the radiation surface and a function of a balun feeder.
