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...
