Abstract
An electronic device is provided that includes a housing having a first surface facing a first direction, and a second surface facing a second direction opposite to the first direction. The electronic device also includes a conductive pattern having a first conductive coil with an axis that is substantially perpendicular to the first direction or the second direction. The electronic device additionally includes a communication circuit configured to cause the first conductive coil to generate a magnetic flux. The second surface includes a first region made of a conductive material and a second region made of a nonconductive material. When viewed from the second surface, the first conductive coil is disposed mostly under the first region. The first conductive coil is configured to include a first section disposed near or on the second region to cause the magnetic flux to pass through the second region.
