The embodiment of the invention discloses a feed network of a base station antenna, a base station antenna, and a base station. The feed network of a base station antenna includes strip-shaped line cavity structures and microstrip line circuits, wherein the each microstrip line circuit is arranged at the front surface of a reflecting plate, and is parallel to the reflecting plate; the each microstrip line circuit is internally provided with a first conductor strip and a dielectric substrate; the each microstrip line circuit is connected with the front surface of the reflecting plate; the dielectric substrate is arranged at the middle part between the first conductor strip and the reflecting plate; the each strip-shaped line cavity structure is arranged at the back surface of the reflectingplate, and first avoidance holes are formed in the reflecting plate; the each strip-shaped line cavity structure is internally provided with at least one second conductor strip; and the each strip-shaped line cavity structure is arranged at the back surface of the reflecting plate, and the second conductor strip penetrates through the first avoidance holes to connect with the first conductor strip in the corresponding microstrip line circuit. The invention also provides a base station antenna and a base station. The feed network of a base station antenna is simple in structure and is easy forassembling and production.
Description
technical field [0001] The present application relates to the communication field, and in particular to a feed network of base station antennas, base station antennas and base stations. Background technique [0002] With the development of equipment and technological progress, the demand for long-distance communication puts forward higher and higher requirements for antenna gain. The formation of multiple antenna arrays can effectively increase the electrical size of the antenna, thereby providing higher gain. [0003] Currently, conventional base station antennas such as figure 1 As shown, the inside of the radome includes three parts, namely: a radiation array unit 101, a reflector 102 for constraining orientation, and a feed network installed on the reflector to provide the amplitude and phase of the radiating unit. [0004] exist figure 1 In the conventional structure, for example, the feed network generally includes devices such as a phase shifter 103, the radiation u...
