Title:
NFC ANTENNA OF HANDHELD DEVICE, AND HANDHELD DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/104208
Kind Code:
A1
Abstract:
The present invention belongs to the field of NFC antennas. Disclosed are an NFC antenna of a handheld device, and a handheld device. The NFC antenna of a handheld device comprises an antenna substrate and a closed coil, wherein the closed coil is arranged along the edge of the antenna substrate; and the antenna substrate comprises a first antenna substrate and two second antenna substrates, which are integrally arranged, the first antenna substrate being used to be arranged on the back face of the handheld device, and two sides of the first antenna substrate in the width direction of the handheld device respectively being bent and extending towards the front face of the handheld device to form the two second antenna substrates. In the present invention, two sides of an NFC antenna are bent towards the front face of a handheld device, such that the front face of the handheld device can sense NFC antenna signals, which are located at two sides of the NFC antenna, such that an NFC card can be swiped on both the front face and the back face of the handheld device. By means of the present invention, double-sided reading and writing are realized by means of one NFC antenna, and compared with two antennas being required for realizing double-sided reading and writing in the prior art, the overall thickness of a machine of the present solution is smaller, and the cost of the machine is lower.
