Abstract

The invention relates to an SIM antenna capable of balancing a communication distance in a mobile payment transfer bridge scheme. The SIM antenna is formed by connecting a spiral winding coil of a bottom metal of an SIM card and a spiral winding coil of a top metal of the SIM card in series by two through holes, wherein the spiral winding coils are arranged on the edge of the SIM card and mutually interleaved but not laminated. Two ports of the antenna are arranged the circuit connection position on the SIM card in the antenna coils and the middle of the antenna is used for encapsulating a chip of the SIM, an SIM chip of a QSIM and correlated circuits. When a mobile phone with strong shield is designed to receive signal and the resonance is 13.56MHz, the antenna inductance of the mobile phone with weak shield is increased, the antenna automatically detunes and the receiving signal is less amplified or suppressed; the circuit in the mobile phone with strong shield is matched with the antenna impedance at an emission frequency of 6.78MHz in an impedance matching network, the antenna inductance value of the mobile phone with weak shield is increased, the automatic impedance match detunes, the emission power is reduced, the communication distances of different mobile phones are balanced, the dispersion of the communication distances of the mobile phones is reduced, thus the mobile phone communication distance control without calibration is realized.

Description

technical field [0001] The invention relates to an antenna, in particular to a SIM antenna with balanced communication distance for a mobile payment transfer bridge. 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. Currently, existing mobile payment technology solutions include: a dual-interface SIM card solution (DI-SIM), a near field communication (Near Field Communication, NFC for short) 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 communication frequency...
