Embodiment Construction

[0072] 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.

[0073] 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 said to be "electrically connected" to another element, it may be connected by contact, eg, by a wire, or non-contact, eg, by a non-contact coupling.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same mea...

Abstract

The invention provides an antenna structure which is arranged on the carrier of a wireless communication device. The antenna structure comprises a first radiator, a second radiator, a feeding portion,a first ground portion, and a second ground portion. The first radiator is a loop antenna which is arranged on at least three different planes of the carrier, and both ends are electrically connectedwith the feeding portion and the first ground portion. The second radiator and the first radiator are spaced apart from each other. The second radiator is arranged on at least two different planes ofthe carrier. The second radiator is electrically connected with the second ground portion. The first radiator feeds current from a feed source through the feeding portion. The second radiator is coupled to the first radiator to acquire current. The invention further provides the 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 toward lightness and portability, and consumers' requirements are also getting higher and higher. In some designs of wireless communication devices, in the limited design space of the antenna structure, it is necessary not only to obtain a larger radiation bandwidth, but also to coordinate with the placement space of other electronic components, such as wires. In addition, wires cause the radiation bandwidth of the antenna to be reduced, resulting in poor radiation performance of the antenna. Contents of the invention [0003] In view of this, it is necessary to provide an antenna structure and a wireless communication device with the antenna structure. [0004] An antenna structure arranged on a ...
