Problems solved by technology

The above-mentioned NFC antenna structure is obviously not suitable for wearable devices such as watches. This is because when people wear watches, if the NFC antenna is placed on the back of the watch according to the design of the mobile phone, it is difficult to realize NFC antenna communication at this time, which seriously affects Communication effect of NFC antenna

Embodiment Construction

[0029] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0030] The most critical idea of ​​the present invention is that: the antenna radiation body of the NFC antenna assembly adopts a single-turn non-closed metal coil or metal ring design, the structure is simpler, the occupied area and space are small, and it is conducive to thinner and miniaturized design; The first inductance and the second inductance can increase the inductance value of the antenna radiator as a single-turn non-closed metal coil or metal ring, and the capacitance value of the antenna radiator can be increased through the capacitance, and the number of turns of the metal coil can be reduced to a single turn. The antenna occupies a smaller area and volume, and has a simpler structure, is suitable for wearable devices such as smart watches, and has...

Abstract

The invention discloses an NFC antenna structure applied to a wearable device and an intelligent watch. The NFC antenna structure comprises an antenna radiation body, an adjustment circuit assembly, a first feed part and a second feed part, wherein the antenna radiation body is a single-turn metal coil with an opening, and the opening divides the metal coil into a non-closed annular structure; the adjustment circuit assembly comprises a first inductor, a second inductor and a capacitor, and the first inductor and the second inductor are connected in series and then overall connected with the capacitor in parallel. The first inductor and the second inductor connected in series increase the inductance value of the radiation body which is the single-turn non-closed metal coil or metal ring, the capacitor increases the capacitance of the radiation body, the turn number of the metal coil is reduced to one, the occupied space and size of the antenna are small, and communication quality is reliable.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an NFC antenna structure for a wearable device and a smart watch. Background technique [0002] In recent years, wearable devices have attracted more and more attention. As an important member of wearable devices, smart watches are developing rapidly. So far, many mobile phone manufacturers (such as Apple, Motorola, and Samsung, etc.) have started to manufacture smart watches. Of course, in order to establish a wireless connection and communication with peripheral devices (such as mobile phones, etc.), the smart watch must support a certain wireless communication protocol (such as Bluetooth, etc.). On the other hand, the increasingly popular NFC communication has become a standard feature of smartphones. NFC is a non-contact identification and interconnection technology with a working frequency of 13.56MHz, which is suitable for short-distance communication in mobile phones, ...
