Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention is clearly and completely described below in conjunction with the embodiments and accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] Figure 4 It is the SIM magnetic field analysis diagram of Apple mobile phone. Helical antenna coil 41 on the SIM card, which sends and receives signals of the reader operating frequency; by figure 1 As shown, the card slot 10 of the SIM card is metal, so the leakage magnetic field at the bottom of the SIM card is very small, and the leakage magnetic field at the top of the SIM card, that i...

Abstract

The invention provides a passive-signal enhancement antenna sheet for an iphone full-card NFC scheme. An antenna is in the form of a sheet when unfolded. According to the passive-signal enhancement antenna sheet, a flexible circuit board and the antenna with metal additionally arranged on an equivalent flexible substrate or the antenna with a wound fine metal wire are adopted. The antenna comprises a small-sized spiral coil and a large-sized spiral coil which are connected in series. The shape of the small-sized spiral coil is similar to a rectangle. The size of the small-sized spiral coil is identical to the size of the portion, on the side surface of an iphone, of an iphone card support, and the small-sized spiral coil is arranged outside the card support of a SIM card on the side surface of the iphone. The large-sized coil is folded to the back surface of the iphone. The size of the large-sized coil is not larger than the size of the back surface of the iphone. By the adoption of the passive-signal enhancement antenna sheet for the iphone full-card NFC scheme, the defect that it is difficult for a reader to receive sent signals of the SIM card of the iphone is overcome, the shape of the SIM card and the universality of the iphone are not changed, and the communication mode with durability and high robustness is also achieved.

Description

technical field [0001] The invention relates to a dual-frequency communication antenna, in particular to a passive signal enhancement antenna post for Apple's full card NFC scheme, and a passive antenna for mobile payment mobile phone SIM card signal enhancement. Background technique [0002] Mobile money will become one of the most important development trends in the next few years, which will bring new benefits to users around the world and have a profound impact on industries such as telecommunications, technology and financial services. At present, existing solutions of mobile payment technology include dual-interface SIM card (DI-SIM), near field communication (Near Field Communication, NFC for short) and 45GHz RFSIM. [0003] Near field communication NFC: [0004] NFC was jointly proposed by Philips, Nokia, Sony and other manufacturers. It combines radio frequency card reader, contactless card and point-to-point functions on a single chip, and is a short-distance wir...
