The invention provides a double-sided board wire-based NFC (Near Field Communication) antenna and an electronic device. The antenna comprises copper electric conduction wires, a base material, adhesive bodies, an ink layer and copper through holes; one surface of one copper electric conduction wire is bonded onto one surface of the base material, and the corresponding adhesive body is bonded onto the other surface of the copper electric conduction wire; one copper electric conduction wire is bonded onto the other surface of the base material; the copper through holes of the base material are connected with the copper electric conduction wires at the two surfaces of the base material; and the copper electric conduction wires at the two surfaces of the base material are overlapped completely or partially. Compared with a conventional NFC antenna, the double-sided board (FPC) overlapped copper electric conduction wire-based NFC (Near Field Communication) antenna of the invention is enhanced in eddy-current effect and improved in overall radio frequency performance since the length of the copper electric conduction wires is increased in a limited area.
Description
technical field [0001] The invention relates to the field of NFC antenna design, in particular to an NFC antenna based on double-panel wiring, and in particular to an NFC antenna and electronic equipment based on double-panel FPC overlapping copper conductive wiring. Background technique [0002] The full name of NFC in English 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. NFC is a wireless connection technology that provides easy, safe and fast communication. , NFC has the characteristics of short distance, high bandwidth and low energy consumption. At present, the mainstream NFC antenna wiring is double-sided single-sided copper conductive wiring. The NFC antenna with copper conductive traces can increase the length of the copper conductive traces in a limited area, and the double-sided copper conductive traces increase the magnetic f...
