Abstract

The invention discloses a low near-field radiation mobile communication device, which comprises a circuit board, a ground plane, an antenna component and a first inductive coupling component, wherein the ground plane is positioned on the circuit board, and is provided with a first side edge and a second side edge; the antenna component is positioned on the circuit board or in the vicinity of the circuit board, and has a first working frequency band and a second working frequency band; the first inductive coupling component is positioned on the first side edge of the ground plane, and is provided with a sheet metal and an inductive component; the sheet metal is electrically connected to the ground plane by the inductive component; and the first inductive coupling component generates a resonance mode at given frequency in the second working frequency band so as to reduce the surface current excitation on the ground plane and further reduce field quantities of a near-field radiation electric field and a magnetic field of the low near-field radiation mobile communication device in the second working frequency band. The near-field radiation electric field energy of the low near-field radiation mobile communication device provided by the invention is effectively reduced.

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...
