Abstract

The invention discloses a dual-frequency communication vertically folded mobile phone cable patch antenna for mobile payment service mobile phones. The antenna cable patch comprises a 13.56 MHz antenna and a 6.78MHz antenna, wherein the antennae both are spirally coiled rectangular coils, the 13.56 MHz antenna is metallically isolated from a back cover of the mobile phone via a magnetic film, the 6.78MHz antenna is vertical to the 13.56 MHz antenna and covers the mobile phone side near an SIM (Subscriber Identity Module) insertion part, and the 13.56 MHz antenna and the 6.78MHz antenna are packaged in a back-off manner through a back-off pad and a chip. The dual-frequency communication vertically folded mobile phone cable patch antenna has the following advantages that the mutual influence between the 13.56 MHz antenna and the 6.78MHz antenna is low, a receiving antenna of the 6.78MHz antenna is less blocked by adjacent-channel signals, the coupling factor of a communication antenna between the 6.78MHz antenna and the SIM is high, and the cable patch is guaranteed to receive the signals transmitted by the SIM; and the 6.78MHz antenna also can be a signal amplifier between the SIM antenna and a reader antenna, thereby increasing the signal transmission between the SIM antenna and the reader antenna.

Description

technical field [0001] The invention relates to an antenna, in particular to a QSIM dual-frequency communication wire-attached antenna for a mobile payment service mobile phone. 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, the existing solutions of the mobile payment technology include a dual-interface SIM card solution (DI-SIM), a near field communication (Near Field Communication, NFC) solution, and a 2.45GHz RFSIM solution. [0003] NFC scheme: [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 wireless communication technology. NFC adopts 13.56MHz as the communicat...
