Embodiment Construction

[0078] 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 attached drawings, for detailed description as follows.

[0079] 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 achi...

Abstract

Provided is an antenna structure. The antenna structure comprises a metal mechanism part, a dielectric substrate, a feed-in radiation part, a coupling radiation part, a ground plane, a first short circuit part, a second short circuit part and a circuit element; the metal machine part is provided with a slotted hole; the dielectric substrate is provided with a first surface and a second surface which are opposite to each other; the feed-in radiation part extends and crosses the slotted hole; the coupling radiation part is adjacent to the feed-in radiation part; the first short circuit part is coupled to a first grounding point on the grounding surface; the second short circuit part is coupled to the metal machine component; the circuit element is coupled between the first short circuit part and the second short circuit part; and the coupling radiation part is arranged on the first surface of the dielectric substrate, and the feed-in radiation part is arranged on the second surface of the dielectric substrate. The antenna structure has the advantages of small size, wide band, low manufacturing cost and the like, so that the antenna structure is very suitable for being applied to various mobile communication devices.

Description

technical field [0001] The present invention relates to an antenna structure (Antenna Structure), in particular to a broadband (Wideband) antenna structure. 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] Antenna is an indispensable element in...
