NFC (Near Field Communication) antenna and electronic equipment

Abstract

The invention belongs to the antenna field, and specifically discloses an NFC (Near Field Communication) antenna arranged in electronic equipment. The NFC antenna comprises an insulating substrate having a bearing surface and coils arranged on the bearing surface, wherein the coils comprise an NFC coil and a wireless charging induction coil used for receiving an external radio-frequency signal and charging the electronic equipment. The invention also provides the electronic equipment comprising the above NFC antenna. Compared with the prior art, the NFC antenna provided by the invention comprises the NFC coil and the wireless charging induction coil capable of charging the electronic equipment, by arranging the NFC coil and the wireless charging induction coil on the same insulating substrate, space can be saved, and the function of wireless charging also can be realized. The electronic equipment applying the NFC antenna not only can realize a communication function, but also can realize a wireless charging function, thus the use is more convenient.

Description

technical field [0001] The invention belongs to the field of antennas, and in particular relates to a near-field communication antenna and electronic equipment using the same. Background technique [0002] Near Field Communication (NFC, Near Field Communication) is a technology that uses electromagnetic induction to send and receive electromagnetic waves to realize short-distance wireless communication between electronic devices, and thus gave birth to electronic devices such as mobile phones with near-field payment functions. It has largely changed the way people use some everyday devices, especially credit cards, keys and cash. [0003] With the development of communication technology, users have higher and higher requirements for the convenience of portable electronic devices (such as mobile phones, digital cameras, etc.), some electronic devices have non-standard charging ports, and some even standard charging ports of users also want to request the function of wireless...

Problems solved by technology

[0004] However, the inventors of the present invention have found that current electronic devices, such as mobile phones, have increasingly compact internal structures and require more and more functions. Many near-field communication antennas only have communication functions. If wireless charging is required, Additional modules are required for wireless charging, which requires a larger space
