Problems solved by technology
However, in the case of multiple antennas (for example, devices including multiple antennas under the long-term evolution LTE standard), it is difficult to ensure high antenna efficiency while maintaining low correlation between antennas
The above problems are caused by the small size of handheld electronic devices, and it is difficult to obtain low correlation between antennas by keeping a certain distance between them
Or, although low correlation is achieved, the antenna efficiency is low

Embodiment Construction
[0048] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0049] Please refer to figure 1 , figure 1 It is a schematic top view of an antenna structure according to an embodiment of the present invention. This embodiment provides an antenna structure formed on the casing of the electronic device. Such as figure 1 As shown, the bottom surface of the housing of the electronic device is used as the ground element 130, and the first cutout 111 and the second cutout 121, the first feed element 112 and the second feed element 122, the switch element 113 and the switch element are formed thereon. 123 to form an antenna structure.
[0050] To further illustrate, the first cutout 111 and the second cutout 121 are located at different sides of the same end of the ground element 130 . The first feeding element 112 is located near the first cutout 111 and electrically iso...

Embodiments of the invention disclose an antenna structure and a wireless apparatus. The antenna structure comprises a grounding element, a first cut, a second cut, a first feed element and a second feed element, wherein the first cut and the second cut are formed in opposite sides of the same end of the grounding element; the first feed element is positioned close to the first cut and is electrically isolated from the first cut; the second feed element is positioned close to the second cut and is electrically isolated from the second cut; electromagnetic coupling between the first feed element and the first cut is realized through an insulating medium which is positioned therebetween; and electromagnetic coupling between the second feed element and the second cut is realized through an insulating medium which is positioned therebetween. By adoption of the technical scheme of the antenna structure and the wireless apparatus, the correlation between antennas can be lowered, and the working efficiency of the antennas can be improved.
Description
technical field [0001] The invention relates to the communication field, in particular to an antenna structure and a wireless device. Background technique [0002] In the prior art, multiple antenna structures have been introduced in handheld electronic devices. However, in the case of multiple antennas (for example, a device including multiple antennas applied under the Long Term Evolution LTE standard), it is difficult to ensure high antenna efficiency while maintaining low correlation between antennas. The above-mentioned problems are caused by the small size of the handheld electronic device, and it is difficult to obtain a low correlation between the antennas by keeping a certain distance between the antennas. Or, although low correlation is achieved, the antenna efficiency is low. The antenna efficiency is the ratio of antenna radiation power to antenna input power. Contents of the invention [0003] In view of this, the embodiments of the present invention expect...
