Embodiment Construction

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] It should be noted that when an element is referred to as being "electrically connected" to another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "electrically connected" to another element, it may be connected by contact, eg, by a wire connection, or non-contact, eg, by a non-contact coupling.

[0063] Unless otherwise defined, all technical and scientific terms used herein ...

Abstract

An antenna structure, comprising a radiating part, a grounding part, a feed-in part, a metal frame and a first matching circuit, the metal frame has a first breakpoint, and the first breakpoint forms a first breakpoint on one side of the metal frame. a radiating section, the radiating section is connected to the feed-in section and the grounding section and arranged at intervals inside the metal frame, and is electrically connected to the first radiating section, and one end of the first matching circuit is electrically connected to The first radiating section is close to one end of the first breakpoint, the other end of the first matching circuit is electrically connected to the ground part and connected to the ground, and the feeding part feeds current to the radiating part, the Both ends of the first radiation section and the first matching circuit are used to excite radiation signals in the first frequency band. Also provided is a wireless communication device with the antenna structure.

Description

technical field [0001] The invention relates to an antenna structure and a wireless communication device with the antenna structure. Background technique [0002] With the advancement of wireless communication technology, wireless communication devices are constantly developing towards a thinner and lighter trend, and consumers have higher and higher requirements for product appearance. Due to the advantages of metal casings in terms of appearance, structural strength, and heat dissipation effects, more and more manufacturers design wireless communication devices with metal casings, such as backplanes, to meet the needs of consumers. However, the metal shell easily interferes and shields the signal radiated by the antenna disposed therein, and it is not easy to achieve broadband design, resulting in poor radiation performance of the built-in antenna. Furthermore, the backplane is usually provided with slots and breakpoints, which will affect the integrity and aesthetics of ...
