Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] figure 1 A schematic diagram showing the structure of the NFC antenna described in the embodiment of the present invention.

[0022] see figure 1 As shown, the NFC antenna includes: a metal frame 10 of a terminal device for receiving NFC signals; an antenna circuit 20 connected to the metal frame 10 for processing the NFC signal so that the terminal device uses the NFC signal Realize short-range wireless communication.

[0023] In the above technical solution of this embodiment, the metal frame 10 of the terminal device is used instead of the traditional FPC antenna combined with ferrite, not only can successfully receive the NFC signal, but also the circuit matching and debugging is simple, and there is no need to pre-install the terminal ...

Abstract

The invention discloses an NFC antenna and terminal equipment for receiving NFC signals. The NFC antenna comprises a metal frame of the terminal equipment for receiving NFC signals, and an antenna circuit connected with the metal frame and used for processing the NFC signals, so that the terminal equipment can use the NFC signals to realize near field communication. According to the technical scheme of the invention, the NFC antenna can complete high-sensitivity NFC signal reception only by using the metal frame of the terminal equipment as the NFC antenna carrier without needing an FPC (flexible printed circuit) antenna manufactured by combining a flexible printed board with ferrite or binding an antenna on the rear casing of a cell phone battery; the material cost of the NFC antenna is saved by using the existing structure of the terminal equipment.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to an NFC antenna and terminal equipment. Background technique [0002] At present, most NFC (Near Field Communication, short-range wireless communication) antennas are combined with FPC (Flexible Printed Circuit, flexible printed circuit board) antennas and ferrite, and are attached to the back shell of the mobile phone battery. In fact, ferrite materials are needed to overcome the impact of the battery on the performance of the NFC antenna, so the cost is relatively expensive, and it is not conducive to the design of ultra-thin mobile phones. [0003] Therefore, the NFC antenna in the prior art has the problems of low product performance and high production cost. Contents of the invention [0004] The invention provides an NFC antenna and a terminal device, which are used to solve the problems of low product performance and high production cost of the NFC antenna in the prior...
