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.

A feeding network of a dual-beam antenna, comprising:
- a cavity, comprising an upper grounding metal plate and a lower grounding metal plate;
- a printed circuit board (PCB), disposed inside of the cavity, the PCB comprising:
- a splitting network circuit configured in strip line, and
- a phase-shift circuit configured in strip line;
- and
- at least two radio-frequency signal input ports connected to the splitting network circuit on the PCB, and after sequentially passing through the splitting network circuit and the phase-shift circuit on the PCB, radio-frequency signals that are input from the at least two radio-frequency signal input ports form, by using an antenna element of the dual-beam antenna, at least two beams between which there is an angle.
