Embodiment 1

[0031] Such as figure 1 As shown, the present invention provides the application of a novel laminated parallel structure NFC antenna in a mobile terminal, and the parallel wiring in the entire NFC antenna is all the wiring of the entire antenna; by setting the stacked multi-faceted parallel antenna wiring, more Fewer antenna coils and lower DCR values ​​produce the same inductance, significantly reducing antenna impedance and current loss, which can effectively improve the utilization of the magnetic field and improve antenna performance.

[0032] This new type of stacked parallel structure NFC antenna is used in various mobile terminals such as mobile phones, PDAs, and computers. Now the mobile terminal technology is developing rapidly, and the mobile terminal is optimized in the direction of lightness, thinness, and miniaturization. In short supply, the area left for the antenna is also continuously reduced. The multi-faceted parallel antenna wiring can be set up in a certai...

Embodiment 2

[0049] Such as image 3 As shown, the present invention provides the application of a novel laminated parallel structure NFC antenna in a mobile terminal. The parallel wiring in the entire NFC antenna is a partial wiring of the entire antenna, and is in the form of a single-section partial parallel connection; Type antenna routing can produce the same inductance with fewer antenna coils and lower DCR values, significantly reducing antenna impedance and current loss, which can effectively improve the utilization of the magnetic field and improve antenna performance.

[0050] Such as image 3 As shown, the NFC antenna includes a substrate 1 and a first wiring 3 and a second wiring 5 respectively arranged on the first surface 2 of the substrate 1 and a second wiring 5 on the second surface 4; the first wiring 3 and the second wiring 5 are The same routing direction is arranged in parallel, and the first routing 3 and the second routing 5 are connected through the via hole 6 . T...

Abstract

The invention discloses a novel stacked parallel structure NFC antenna applied to a mobile terminal. The antenna is applied to the mobile terminal and comprises a substrate, and a first wire and a second wire respectively arranged on a first surface and a second surface of the substrate, wherein the first wire and the second wire are identical in wire directions and are arranged parallelly, and the first wire and the second wire are communicated through conduction holes. The invention further discloses the mobile terminal equipped with the novel stacked parallel structure NFC antenna. The novel stacked parallel structure NFC antenna and the mobile terminal are advantaged in that the structure is compact and simple, antenna impedance is substantially reduced, current loss is reduced, a magnetic field utilization rate is effectively improved, and antenna performance is improved.

Description

technical field [0001] The invention relates to the field of communication, in particular to the application of a novel laminated parallel structure NFC antenna in a mobile terminal. Background technique [0002] An antenna is a device that uses frequency characteristics to receive and transmit signals. In recent years, with the development of wireless terminals and communication technologies, Near Field Communication (NFC) has been deeply researched and widely used. NFC technology begins with Radio Frequency Identify Detection (RFID) technology, which combines an inductive card reader and an inductive card on a single chip to realize point-to-point data exchange. Through the NFC function, mobile phones, PDAs, computers and other devices can easily realize wireless connection and data sharing. [0003] With the rapid development of mobile terminal technology and the continuous upgrading of electronic products, the optimized design of mobile terminals in the direction of li...
