Abstract

A low near field radiation mobile communication device. The low near field radiation mobile communication device includes: a circuit board; a ground plane located on the circuit board, the ground plane having a first side and a second side; an antenna component located on the circuit board or Adjacent to the circuit board, the antenna component has a first operating frequency band and a second operating frequency band; and a first inductive coupling component is located on the first side of the ground plane, the first inductive coupling component has a metal The metal piece is electrically connected to the ground plane through the inductor element, and the first inductive coupling component generates a resonance mode at a specific frequency in the second operating frequency band to reduce the noise on the ground plane. The surface current is excited, so that the near-field radiation electric field amount and magnetic field amount of the low near-field radiation mobile communication device in the second operating frequency band are reduced. The invention effectively reduces the amount of near-field electromagnetic fields of low-near-field radiation mobile communication devices.

Description

technical field [0001] The invention relates to a mobile communication device, in particular to a low near-field radiation mobile communication device. Background technique [0002] With the rapid development of wireless communication technology, a variety of wireless communication products are constantly being introduced. Mobile communication devices have an inseparable relationship with people's lives, and mobile phones are the most important communication products. At present, in addition to considering the antenna's working bandwidth coverage and the antenna's far-field radiation efficiency, the antenna's electromagnetic field distribution in the near-field has gradually been paid attention to. [0003] The United States Federal Communications Commission (FCC) stipulates that most mobile phones sold in the United States need to pass the specification requirements of hearing aid compatibility (HAC, Hearing Aid Compliance). The user of the hearing aid will not be interfer...
