Problems solved by technology

[0007] In order to solve the problem that the existing RFID antenna needs to be manufactured separately, the cost is high, and it is prone to poor contact, the present invention provides an integrated structural design of the RFID antenna. By integrating the RFID antenna into the main board of the terminal, the antenna Reliable connection, and the overall thickness and cost of the terminal are significantly improved

Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] In this embodiment, a mobile phone is taken as an example to describe the structural design of the RFID antenna in detail.

[0024] For the traditional UIM card, there are generally 6 pins, which are installed in the card holder of the mobile phone terminal, just in contact with the 6 contacts C1~C6 in the card holder, and cooperate with the mobile phone antenna to complete the regular communication function of the mobile phone . For the dual-interface UIM card, in order to realize the connection with the RFID antenna, two antenna pins are added on the basis of the existing pins to realize the identification function of the radio frequency signal. In contrast, for mobile terminals that support the payment function, the number of contacts in the deck is also increased from 6 to 8 C1-C8, such as figure 1 As shown, after the dual-interfa...

Abstract

The invention discloses an integrated structure of a radio frequency identification (RFID) antenna and a mobile communication terminal. The RFID antenna is formed by printed circuit board (PCB) wires distributed on a mainboard in the terminal. Feed points of the RFID antenna are connected with antenna contacts arranged on a card seat on the mainboard by the internal PCB wires. The antenna contacts are right in contact with antenna pins of an RFID chip after a smart card integrated with the RFID chip is inserted into the card seat. The design of the antenna provided by the invention is directly finished on the mainboard in a way of adopting the PCB wires, and a structural contact way is avoided, so the connecting reliability is greatly improved. Simultaneously, the positions of the wires of the RFID antenna are determined on the surface, away from a battery, on the mainboard, thereby ensuring that a sufficient distance can be reserved between the RFID antenna and a battery core to further greatly weaken eddy effects of metals without arranging an additional ferrite film and achieve the great advantages of reduction in terminal cost.

Description

technical field [0001] The invention belongs to the technical field of mobile communication terminals, and in particular relates to an integrated structural design of an RFID antenna and a mobile communication terminal adopting the structural design of the integrated RFID antenna. Background technique [0002] The currently commercialized mobile payment solution is China Telecom's dual-interface mobile payment UIM card solution, which integrates RFID chips into the UIM card and is called a dual-interface card. The dual-interface card has two working interfaces, contact and non-contact. The contact interface realizes the SIM / UIM card function of the operator, and the non-contact interface realizes non-operator functions, such as mobile payment functions such as mobile phone card swiping and electronic wallet. In order to realize the data interaction between the RFID chip and special reading and writing equipment (such as POS machines, etc.), an RFID antenna needs to be added ...
