Description
Technical Field
The application relates to the field of antenna design of mobile terminals, in particular to an antenna system of a mobile terminal and the mobile terminal.
Background
In recent years, Near Field Communication (NFC) has been intensively studied and widely used with the development of wireless terminals and Communication technologies. The NFC technology starts with a Radio Frequency Identification (RFID) technology, in which an inductive card reader and an inductive card are combined on a single chip to implement a point-to-point data exchange function. Through the NFC function, wireless connection and data sharing are conveniently achieved among multiple devices such as mobile phones, PDAs and computers.
With the rapid development of mobile terminals, mobile terminals having a metallic texture will continue to be popular for a future period of time. In view of various structures of metal materials, antenna signals of mobile terminals become a challenge in the industry. Because the metal casing can shield electromagnetic radiation, lead to NFC's coil unable and the space beyond the metal casing to carry out the communication, greatly destroy the effect that has influenced the communication.
In the design of the NFC antenna of the mobile terminal with the metal housing, the existing technical solution is as shown in fig. 1, the metal housing 001 is perforated at the rear camera 002 to avoid the camera, and the metal slot right in front is slotted to form an NFC antenna slot 003, the left side of the slot is connected to the NFC first feed point 004, and the right side of the slot is connected to the NFC second feed point 005, so that an NFC current loop is formed. However, this solution limits the rear camera to be centered only, and the metal casing must be slit, which deteriorates the integrity of the appearance, and therefore, there is a need for an improved antenna solution to solve the above problems.
In view of the above problems, no effective solution has been proposed.
