Abstract

Some embodiments of the present invention relate to the technical field of electronic products, and disclose an antenna device and electronic equipment. In the embodiment of the present invention, the antenna device is applied in electronic equipment including a circuit board; the antenna device includes: a SAR-reducing branch and an antenna arranged on the circuit board; the SAR-reducing branch includes at least a capacitive sensor; the SAR-reducing branch is connected to Antenna, and there is a preset distance between the capacitive sensor and the antenna; wherein, the sensing channel of the capacitive sensor and the adjacent reference channel are respectively connected to the antenna in the form of wiring. Some embodiments of the present invention also provide an electronic device. The embodiment of the present invention suppresses common-mode noise signals and greatly improves circuit stability.

Description

technical field [0001] Some embodiments of the present invention relate to the technical field of electronic products, in particular to an antenna device and electronic equipment. Background technique [0002] Mobile phones, computers and other electronic devices are widely used in people's daily life, and the terminal is usually relatively close to the human body. In order to keep the influence of the electromagnetic waves radiated by the antenna in the terminal on the human body within a safe range, CE certification and FCC certification have strict requirements on SAR ( Electromagnetic wave specific absorption rate) requirements are also more stringent, therefore, the antenna in the terminal must meet the SAR index requirements. [0003] At present, the use of capacitive sensors to achieve SAR reduction is the mainstream SAR reduction solution. In the existing SAR reduction circuit, the capacitive sensor is connected to any antenna that needs to reduce SAR through single-...
