Embodiment Construction

[0065] 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.

[0066] Certain terms are used in 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 "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 error range a...

Abstract

An electronic device comprises a proximity sensor, an antenna structure and a sensing plate. The antenna structure comprises a first radiation part and a second radiation part which are separated from each other and adjacent to each other, wherein the first radiation part is provided with a feed-in point, and the second radiation part is coupled to a ground potential. The sensing plate is adjacent to the antenna structure. The sensing board comprises a main branch, a first branch and a second branch, the main branch is coupled to the proximity sensor, the first branch is coupled to a first connection point on the main branch, and the second branch is coupled to a second connection point on the main branch. The second branch has a winding shape. The antenna structure may cover a first frequency band and a second frequency band, wherein a resonant frequency of the sensing plate falls neither within the first frequency band nor within the second frequency band.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device capable of integrating a sensing plate and an 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 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, 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 components are a...
