Abstract

The invention relates to a wideband antenna, which comprises a dielectric, a radiator and a grounding surface. The radiator includes a main conductor, a feed-in conductor, a coupling conductor, an extension conductor and a short-circuit conductor, and the radiator is attached on the dielectric surface. The dielectric and the radiator are adhered on the grounding surface, and the main conductor isused for adjusting a first resconance mode of the antenna. The coupling conductor includes a first coupling portion and a second coupling portion with a gap therebetween, wherein the first coupling portion is connected with the feed-in conductor; the second coupling portion is connected with the main conductor; and the extending conductor is connected with the first coupling portion of the coupling conductor and extends along the end portion of the dielectric for adjusting the second resconance mode of the antenna. The radiator can effectively adjust the multi-frequency resconance mode of theantenna, and the antenna can be tightly fixed on the grounding surface to simplify the antenna assembly program.

Description

technical field [0001] The invention relates to a broadband antenna, in particular to an antenna for adjusting multi-frequency resonance modes. Background technique [0002] The rapid development of wireless communication technology has created huge business opportunities for communication electronic products. The most critical technology is the antenna. The antenna is the starting point and the end point of the wireless communication system, and its characteristics will affect the quality of communication. In recent years, the continuous emergence of various communication systems and applications has also made the demand for antennas move toward broadband antenna designs covering multiple system frequency bands; at the same time, due to the appearance of electronic products tending to be thinner and miniaturized, antenna design , It also needs to have the characteristics of miniaturization. How to reduce the size of the antenna and have broadband characteristics has become ...
