Beam tilt antenna

The invention provides a beam tilt antenna, and relates to the technical field of antennas. The beam tilt antenna comprises a cavity, a cover plate, a radiator and a coaxial line, the top of the cavity is opened, the cover plate is arranged at the top opening of the cavity and seals the cavity, the radiator is arranged in the cavity and is electrically connected with the cavity, a first hollow area is arranged on the radiator, a first bevel edge and a second bevel edge are arranged on the radiator, and the first bevel edge and the second bevel edge are arranged on the coaxial line. The first bevel edge is inclined relative to the second bevel edge, a second hollowed-out area is formed between the first bevel edge and the second bevel edge, the first hollowed-out area and the second hollowed-out area are communicated and form a feed gap, the outer conductor of the coaxial line is connected to one side of the feed gap, the inner conductor of the coaxial line is connected to the other side of the feed gap, and a
