Kind Code:
A1
Abstract:
Disclosed is an electronic apparatus comprising: a battery; a coil antenna set to transmit power from the battery; a shielding member located on the lower surface of the coil antenna; and a plurality of magnetic modules formed to surround at least a portion of the side surface of the coil antenna. Each of the plurality of magnetic modules may include: an inner portion facing the side surface of the coil antenna; an outer portion facing the opposite side of the coil antenna; and a non-magnetized region located between the inner portion and the outer portion. The inner portion may include a first inner region and a second inner region located on one side of the first inner region, and the outer portion may include a first outer region and a second outer region located on one side of the first outer region. The first inner region and the second outer region may be magnetized to a first polarity, and the second inner region and the first outer region may be magnetized to a second polarity that is the opposite polarity of the first polarity. Various other embodiments that can be understood through the specification are also possible.
