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 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.

Abstract: Embodiment high-frequency radiator includes two plus and minus 45-degree single-polarized radiators. The single-polarized radiator includes a radiation arm, a balun, a feeder circuit, a filter, and a ground plane. The radiation arm and the balun are electrically connected. The feeder circuit and the balun are separately disposed on two surfaces of a first dielectric plate that is placed vertically. The ground plane is disposed on a downward surface of a second dielectric plate that is placed horizontally. The first dielectric plate is vertically disposed on the second dielectric plate, and the filter includes a capacitor branch and an inductor branch. The inductor branch is disposed on a same surface of the first dielectric plate as the balun, the inductor branch is separately electrically connected to the balun and the ground plane, and the capacitor branch is coupled to the ground plane.

Abstract: The present invention provides a base station antenna, including power dividers, network calibration modules, and connectors. The base station antenna further includes at least two phase shifters. At least one phase shifter is integrated with a combiner, the connectors are connected to the network calibration modules, and the network calibration modules are connected to the phase shifters. The one phase shifter integrated with the combiner is connected to the power divider, and at least one output port of the at least one other phase shifter is connected to the phase shifter integrated with the combiner. The base station antenna has an integrated design of phase shifters and combiners, which allows cables in different bands to be shared, reduces a quantity of used cables, is easy to implement in an actual layout and production, facilitates the layout and heat dissipation on the whole, satisfies user requirements, and reduces costs.
