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 specifically cited below, together with the accompanying drawings, to be described in detail 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 "comprising" 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 er...

Abstract

The invention discloses an antenna structure, which comprises a grounding element, a feed-in radiation part, a first radiation part, a second radiation part, a third radiation part and a switching circuit, the grounding element can provide a grounding potential. The feed-in radiation part is provided with a feed-in point. The feed-in radiation part is coupled to the second radiation part through the first radiation part. The third radiation part is coupled to the feed-in radiation part, wherein the feed-in radiation part is arranged between the first radiation part and the third radiation part. The switching circuit can selectively couple the second radiation part to a ground potential according to a control potential. A slot is formed and surrounded by the ground element, the feed-in radiation portion, the first radiation portion, and the second radiation portion.

Description

technical field [0001] The present invention relates to an antenna structure (Antenna Structure), in particular to a wideband (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 laptop computers, mobile phones, multimedia players and other portable electronic devices with mixed functions. In order to meet people's needs, mobile devices usually 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, and 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 component in the ...
