Abstract

Embodiments of the present application relate to the technical field of antennas, and provide an antenna assembly and a terminal. The terminal comprises a non-metal back shell, a main board, a battery, and a coupling coil layer. The inner surface of the non-metal back shell is provided with a heat conductor layer; the heat conductor layer is slotted to form an NFC antenna coil; the main board is disposed opposite to the heat conductor layer, and a feeding point is provided on the main board; the battery and the main board are arranged in a direction parallel to the heat conductor layer; the coupling coil layer is disposed between the main board and the heat conductor layer, and is arranged along with the battery in a direction parallel to the heat conductor layer; the coupling coil layer is connected to the feeding point on the main board; and a space coupling can be formed between the coupling coil layer and the heat conductor layer, so that the heat conductor layer generates secondary radiation.

Description

technical field [0001] The present application relates to the technical field of antennas, and in particular to an antenna component and a terminal. Background technique [0002] With the popularization and development of mobile payment technology, more and more terminals support NFC (Near Field Communication, near field communication technology) function. NFC is a non-contact identification and interconnection technology that can be used in mobile devices, consumer electronics , PC and intelligent control tools for short-range wireless communication. NFC provides a simple, touch-based solution that allows consumers to exchange information and access content and services simply and intuitively. [0003] NFC consists of NFC module and NFC antenna. The NFC module generally consists of a high-speed single-chip microcomputer, a radio frequency chip and a matching circuit. The NFC module is arranged in the main board of the terminal, and the NFC antenna is connected with the f...
