Abstract

The invention discloses a broadband omnidirectional antenna, comprising a floor and a radiator. The radiator is fixed on the floor. The floor is provided with a crack. The length of the crack is smaller than that of the floor. By providing the crack in the floor, the effective dimension of the floor is increased, so that the working bandwidth of the antenna is increased without increasing the physical dimension of the antenna, and the manufacturing cost is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a broadband omnidirectional antenna. Background technique [0002] The radio frequency antenna is an essential hardware facility in the field of wireless communication, and it plays a vital role in the wireless communication system. The radio frequency antenna should have the characteristics of large bandwidth, omnidirectionality, and low cost. In the industrial design of the antenna, attention should be paid to the structural design of the antenna. A good structural design can simplify the antenna structure, reduce the use of manufacturing materials, and reduce manufacturing costs. Therefore, how to design a reasonable and efficient antenna structure is a problem that manufacturers of communication equipment need to consider. [0003] The emitter in the existing bandwidth omni-directional antenna adopts a single-cone structure. This kind of three-dimensional single-cone ...
