Abstract

The invention provides a pre-posed type NFC antenna, and the antenna comprises a screen metal plate. A touch screen is disposed above the screen metal plate, and a coil is disposed below the screen metal plate. The screen metal plate is provided with an opened groove, and the opened groove comprises a groove hole and a gap. One end of the gap extends to the edge of the screen metal plate and is opened, and the other end of the gap is communicated with the groove hole. The vertical projection of a part of the edge of the groove hole is located at an outer side of the edge of a coil. The antenna provided by the invention achieves the reversion of the flowing direction of a current passing through the screen metal plate through employing the opened groove, enables the current to have the same direction with the direction of the body of the coil, and strengthens the NFC antenna. Moreover, because the antenna is disposed below the touch screen, the opened groove on the metal screen plate cannot damage the integrity of a metal housing, and guarantees the beauty of the whole product. Compared with the prior art, the antenna is simple in structure, and is excellent in performance.

Description

technical field [0001] The invention belongs to antennas, and in particular relates to a front-mounted NFC antenna, which is mainly used for terminal equipment such as mobile phones and computers. Background technique [0002] Near field communication (Near Field Communication, NFC)), also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission (within ten centimeters) exchange between electronic devices data. It is widely used in short-distance wireless communication between mobile devices, consumer electronics products, PCs and smart control tools. It can easily realize mobile payment and file transfer, and allows consumers to exchange information, access content and services simply and intuitively. , favored by the majority of customers. [0003] With the rapid development of mobile devices such as smart phones, more and more smart phones use near-field commun...
