Abstract: A feeding network of a dual-beam antenna and a dual-beam antenna are disclosed. The feeding network includes: a cavity, including an upper grounding metal plate and a lower grounding metal plate; a printed circuit board PCB, disposed inside the cavity, where a splitting network circuit and a phase-shift circuit in the feeding network are integrated into the PCB, and arrangement of the PCB and the cavity enables a wire on the PCB to have a strip line structure as a whole; and at least two radio-frequency signal input ports, where the at least two radio-frequency signal input ports are connected to the splitting network circuit on the PCB.
