Description

At present, with the rapid development of electronic and communication technologies, electronic payment using mobile phones has been widely used. NFC technology is widely used in electronic payment, and the design of NFC antennas is very important. The NFC antenna includes a radio frequency unit, a receiving unit, a filtering unit, a matching network unit, and an antenna coil. NFC antennas rely on magnetic field coupling to transfer energy, exchange data and synchronize information. The current practice is to attach a flexible printed circuit board (FPC) printed with an antenna coil to the components of the handheld terminal, and then cover the ferrite material to avoid the metal on the terminal ( For example, the metal material on the battery or the main plate absorbs magnetic field energy, which affects the performance of the NFC antenna. Usually NFC antennas are integrated into the battery back cover, and the NFC antenna can be used as an analog card function and a reader function. When the NFC antenna is used as an analog card function, the user swipes the card transaction, sometimes due to environmental reasons, the signal sent by the reader is relatively weak, and the built-in NFC antenna on the mobile phone does not sense the signal sent by the reader, resulting in The communication with the reader is of poor quality and even the transaction cannot be completed. For example, the user puts the mobile phone in the pocket, and the user is inconvenient to take out the mobile phone for the credit card transaction during the transaction. The signal sent by the reader/writer cannot be sensed by the built-in NFC antenna of the mobile phone due to the barrier of the pocket, and the transaction cannot be performed normally, and the transaction is reduced.

In this embodiment, the short-range communication module may be a 13.56 MHz short-range communication module such as an NFC chip, or a 2.4 GHz short-range communication module.

The mobile terminal of this embodiment can perform close-range communication with an external card reader through an external communication antenna, thereby improving the quality of short-range communication. The communication antenna disposed in the mobile terminal may be a specially made external antenna made of a wire, or an external antenna composed of a wire of a mobile terminal accessory, such as a wire that can be applied with a charger or an earphone. Become an external antenna. In this embodiment, there are many configurations of the communication antenna, and it is only necessary to form a wire of an effective circuit with the short-range communication module. The material of the wire may be a common wire material or a coupling coil material such as copper or aluminum.

Since the communication antenna of the short-range communication module must form a loop with the short-range communication module, it can work. This embodiment describes a way for a communication antenna to form a loop with a short-range communication module:
