Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0033] The current mainstream NFC antenna wiring form is single-ended double-panel. The present invention improves the NFC antenna wiring form into a double-panel parallel wiring antenna, which can connect multiple wirings in parallel in a very small space. Effectively improve the utilization rate of the magnetic field and increase the performance without increasing the loss.

[0034] The wiring mode of the coil of the antenna of the present invention is that multiple wirings are connected in parallel t...

Abstract

The present invention provides an NFC antenna in the form of double-panel parallel wiring. The wiring mode of the coil is that multiple coils are connected in parallel to form a multi-coil parallel closed-loop structure. The planar antenna has at least two parallel closed-loop structures. The entire NFC antenna The parallel wiring can be all the wiring of the entire antenna, or part of the wiring of the antenna, which can be designed according to the environment where the antenna is located. Using the NFC antenna in the form of double-panel parallel wiring can effectively increase the magnetic field utilization rate of the NFC antenna, and can achieve better NFC performance in a smaller area. The NFC performance is affected when the antenna part is covered by metal or not covered by metal. There is a significant improvement. The antenna form can be designed with circuit board materials such as PCB or FPC. Compared with traditional wiring, it has a good appearance and effectively improves the radio frequency performance of the antenna.

Description

technical field [0001] The invention relates to the field of NFC antenna design, in particular to an NFC antenna in the form of double-panel parallel wiring. Background technique [0002] The full English name of NFC is Near Field Communication, near field wireless communication. It is a wireless technology initiated by Philips and jointly promoted by well-known manufacturers such as Nokia and Sony. A pan-European alliance was established by a number of companies, universities and users to develop an open architecture for NFC and promote its application in mobile phones. NFC evolved from the integration of non-contact radio frequency (RFID) technology and interconnection technology. It integrates inductive card readers, inductive cards and point-to-point functions on a single chip, and can communicate with various compatible devices within a short distance. for identification and data exchange. This technology was initially just a simple combination of RFID technology and...
