Problems solved by technology

However, due to the miniaturization of smart devices, the antenna is mostly set close to the metal frame, which makes it easy for the metal frame to generate a current opposite to the antenna, weaken the magnetic field generated by the antenna, and affect the performance of the antenna

Abstract

The invention provides an intelligent device that comprises an annular and closed metal frame and an antenna module. The antenna module is arranged in the metal frame. The antenna module comprises a PCB, a functional coil, a resonance coil and capacitors arranged at two ends of the resonance coil. The PCB is provided with a functional chip, and the functional coil comprises two feeding points which are electrically connected with the functional chip. The resonance coil is arranged between the functional coil and the metal frame and used for resonance induction with the functional coil. The resonance coil in the intelligent device can effectively weaken or counteract a magnetic field caused by reverse current of the metal frame so as to ensure normal work of the antenna module. In addition,the antenna module does not use the metal frame as a radiator, the arrangement of the antenna module is simplified, and the arrangement of other antennas is not influenced.

Description

technical field [0001] The present disclosure relates to the technical field of smart devices, and in particular, to a smart device. Background technique [0002] With the development of communication technology, antennas such as NFC (Near Field Communication, Near Field Communication) and WPC (Wireless Power Consortium, Wireless Power Consortium) are widely used in smart devices such as watches and bracelets. With people's demand for smart devices with beautiful appearance, smart devices often include exquisite and beautiful metal frames or casings. However, due to the miniaturization of smart devices, the antennas are mostly installed close to the metal frame, which makes it easy for the metal frame to generate a current opposite to the antenna, weaken the magnetic field generated by the antenna, and affect the performance of the antenna. Based on this, how to overcome or weaken the influence of the metal frame on the antenna is particularly important. Contents of the i...
