Patent ID: 8423100

Claim:
A mobile communication device with low near-field radiation, comprising an antenna structure, with the antenna structure comprising: a circuit board having a first surface and a second surface opposite to the first surface; a ground plane disposed on the second surface of the circuit board and comprising a first side edge and a second side edge opposite to the first side edge; an antenna element disposed on the first surface of the circuit board or placed near the circuit board, with the antenna element comprising a first operating band and a second operating band; and a first inductively-coupled element disposed on the first surface of the circuit board and located near the first side edge of the ground plane, with the first inductively-coupled element comprising a metal plate and an inductive element, wherein the metal plate is electrically connected to the ground plane through the inductive element; wherein the first inductively-coupled element generates a resonant mode at a specific frequency within the second operating band in order to reduce a surface current excitation on the ground plane and to reduce near-field E-field and H-field strengths of the mobile communication device within the second operating band.
