Embodiment Construction

[0050] 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.

[0051] Certain terms are used throughout the description and claims to refer to particular components. 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 ...

Abstract

An antenna structure includes a ground element and a metal loop. The metal loop includes a main radiation element and a float radiation element. The main radiation element has a feeding point, a firstshorting point, and a second shorting point. The first shorting point and the second shorting point are both coupled to the ground element. The feeding point is substantially positioned between the first shorting point and the second shorting point. The float radiation element is adjacent to the main radiation element and is separated from the ground element and the main radiation element. The ground element is substantially surrounded by the metal loop. Compared with the conventional design, the antenna structure is advantaged by small dimension, wide frequency band, low cost, and low manufacturing complexity. Besides, the antenna structure and a metal appearance assembly of a device can be mutually integrated so that the appearance of the device is beautified, the fashion feeling of thedevice is enhanced, and the antenna structure is applicable to various carrying articles or wearable devices.

Description

technical field [0001] The invention relates to an antenna structure, in particular to an antenna structure that can cover mobile communication frequency bands. 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 communication. [0003] According to the research directio...
