Abstract

An antenna structure includes an antenna holder, a feed unit, a grounding unit, a first radiating unit, a second radiating unit, a third radiating unit, a parasitic unit, and a coupling unit. The feed unit and the grounding unit are positioned on the antenna holder and are spaced apart from each other. The first radiating unit and the third radiating unit are both electrically connected to the feed unit. The parasitic unit is electrically connected to the grounding unit. The first radiating unit couples with the second radiating unit and the parasitic unit. The second radiating unit further couples with the coupling unit and is grounded through the coupling unit.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an antenna structure and a wireless communication device with the antenna structure. Background technique [0002] With the rapid development of software functions and touch screens of wireless communication products, consumers' demand for wireless communication products with large touch screens is increasing. Antenna design space continues to be constrained. At the same time, metal elements around the antenna are likely to cause a shielding effect on the antenna and reduce the transmission characteristics of the antenna. In addition, with the addition of 4G FDD / TDD LTE frequency bands, the demand for antenna bandwidth increases. At present, the antenna design bandwidth needs to cover LTE / GSM / UMTS frequency bands at the same time. It is an urgent problem to be solved in the current field of antenna design to obtain good transmission characteristics. Con...
