Problems solved by technology

No matter which design method is adopted, there will be a problem of metal influence. Its working principle determines that when the magnetic field lines pass through the metal near the antenna, the eddy current effect generated will weaken the magnetic field passing through the antenna, thus affecting the effective use of mobile phones. distance
[0004] In addition, due to the particularity of the position of the RFID antenna and the connection relationship with the UIM card, the RFID antenna is generally attached to a relatively obvious position on the mobile phone case, so there is a possibility of man-made damage, which also makes the mobile phone terminal Reliability is difficult to guarantee

Embodiment 1

[0032] Embodiment one, see figure 1 As shown, the present embodiment sets two antenna terminals J1-1, J2-1 on the mobile phone card holder (such as the UIM holder) of the mobile phone motherboard, and ensures that the two antenna terminals J1-1, J2-1 After the dual-interface UIM card is inserted into the card holder, it just comes into contact with the antenna pin of the RFID chip integrated on the UIM card. An antenna connector J1-2, J2-2 is added on the main board of the mobile phone, and its pads are connected to the antenna terminals J1-1, J2-1 on the deck through PCB traces. In this embodiment, the models of the antenna connectors J1-2, J2-2 can be exactly the same as the battery connectors J3-1, J4-1 set on the motherboard, and can be identical to the battery connectors J3-1, J4-1 1 are located at the same level to facilitate reliable contact with the RFID antenna on the battery when the battery is installed on the mobile phone. The RFID antenna is integrated into the ...

Abstract

The invention discloses a mobile phone with an RFID antenna. The RFID antenna is arranged on a mobile phone battery, an antenna connector is arranged on a mobile phone main board, the antenna connector is connected with two antenna terminals of a mobile phone card cassette, and the two antenna terminals are contacted with antenna pins of an RFID chip when a mobile phone card integrated with the RFID chip is inserted into the cassette; and the antenna connector is connected with an RFID antenna after the mobile phone battery is arranged in the mobile phone. Because the antenna is not exposed, the mobile phone terminal designed by adopting the antenna connecting mode reduces the possibility of man-made damage, and ensures the reliability and safety of using the mobile phone. Meanwhile, a ferrite membrane increased between the RFID antenna and a battery core effectively weakens the influence of metal eddy-current effect on the antenna, and ensures the effective using distance of the mobile phone.

Description

technical field [0001] The invention belongs to the technical field of mobile communication terminals, and in particular relates to a connection structure of an RFID antenna of a mobile phone terminal supporting a payment function. Background technique [0002] With the rapid development of mobile phone terminal chip technology, the functions supported by mobile phones have become more and more colorful. As a new value-added service, the mobile phone payment function is increasingly valued by operators and welcomed by users. The core implementation technology of the mobile payment function is NFC (Near Field Communication) technology, which completes the payment task through non-contact operation with a special card reader. [0003] There are many designs for realizing the mobile payment function on the market at present. China's telecommunications industry currently adopts a design scheme based on a dual-interface smart UIM card with a customized mobile terminal. In terms...
