APPARATUS FOR PARTIALLY SHIELDING MAGNETIC FIELD FROM ANTENNA

摘要

PURPOSE: An apparatus for shielding a magnetic field generated from an antenna is provided to reduce the weight of a shielding unit by using several magnetic cores or forming the shielding unit with a grid type. CONSTITUTION: A magnetic field shielding device includes an antenna(510) and a magnetic core(520). The antenna efficiently emits an electromagnetic wave generated by a wireless transceiver(530) to a space and receives an electric wave of a specific band which is transmitted from the outside. A magnetic core is located on one side of the antenna and includes a protrusion part facing a coil-shaped hollow part of the antenna.
