Embodiment Construction

[0068] In order to make the purpose, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below, together with the accompanying drawings, for detailed description as follows.

[0069]Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The words "comprising" and "including" mentioned throughout the specification and claims are open-ended terms, so they should be interpreted as "including but not limited to". The term "approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and a...

Abstract

The invention discloses an antenna structure, which comprises a first grounding part, a feed-in part, a short circuit part, a parasitic adjustment part, a second grounding part, a first parasitic partand a second parasitic part, wherein the feed-in part is provided with a feed-in point; the feed-in part is coupled to the first grounding part through the short circuit part; the parasitic adjustment part is coupled to the first grounding part; the parasitic adjustment part is at least partially surrounded by the feed-in part, the short circuit part and the first grounding part; the second grounding part is adjacent to the feed-in part; the first parasitic part and the second parasitic part are respectively coupled to the second grounding part; and at least one of the feed-in part, the shortcircuit part, the parasitic adjustment part, the first parasitic part, the second parasitic part, the first grounding part and the second grounding part is arranged on the dielectric substrate. The antenna structure has the advantages of being small in size, wide in frequency band and capable of beautifying the appearance of the device, and is very suitable for being applied to various mobile communication devices.

Description

technical field [0001] The invention relates to an antenna structure (Antenna Structure), in particular to an antenna structure applicable to a mobile device (Mobile Device) with a metal back cover (Metal Back Cover). Background technique [0002] With the development of mobile communication technology, mobile devices have become more and more common in recent years, such as portable computers, mobile phones, multimedia players and other portable electronic devices with mixed functions. In order to meet people's needs, mobile devices generally have a wireless communication function. Some cover long-distance wireless communication ranges, for example: mobile phones use 2G, 3G, LTE (Long Term Evolution) systems and their frequency bands of 700MHz, 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz and 2500MHz for communication, while Some cover short-range wireless communication ranges, for example: Wi-Fi, Bluetooth systems use 2.4GHz, 5.2GHz and 5.8GHz frequency bands for co...
