Antenna device and mobile terminal
This disclosure provides an antenna device including an antenna coil having a plate-shaped magnetic core with first and second main surfaces and a coil conductor wound around the magnetic core, and a flat conductor adjacent to the antenna coil. For instance, the flat conductor can be a ground electrode formed on or within a circuit substrate. The coil conductor includes a first conductor portion adjacent to the first main surface of the magnetic core and a second conductor portion adjacent to a second main surface thereof. The first conductor portion of the antenna coil is closer to an end portion of the flat conductor than the second conductor portion, with the second main surface of the magnetic core facing the flat conductor.
