  • Publication number: 20210151864
    Abstract: This application provides examples of a base station antenna, a switch, and a base station device. A connection status between an output port and an input port of a horizontal-dimensional feeding network is changed by using a switch of the horizontal-dimensional feeding network. In In different connection statuses, quantities of input ports that are connected to a plurality of output ports of the horizontal-dimensional feeding network are different. The input port of the horizontal-dimensional feeding network is in communication with an antenna port to form a transceiver channel. In this case, a quantity of transceiver channels, of the horizontal-dimensional feeding network, formed in each connection status is different. Therefore, the quantity of transceiver channels supported by the base station device can be changed by using the base station antenna without a need of replacing the base station antenna.
