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.
