摘要： An antenna device having a magnetic core to be surface-mounted on a circuit substrate includes a pair of coil portions spaced apart from each other at a predetermined interval. The coil portions are connected by a connecting conductor. An end of the magnetic core includes a curved or bent portion curved toward the circuit substrate. This structure defines an RFID antenna device having an improved receiving sensitivity that can be surface-mounted without increasing the thickness of a casing of a mobile electronic device.

摘要： A portable electronic device includes a circuit board and an antenna coil installed on the circuit board. The antenna coil includes a magnetic core and a coil wound at either side of an unwound portion. The winding direction of the coil is changed at either side of the unwound portion. When the length of the magnetic core is defined as X and the distance between two intersecting points at which a virtual line formed by projecting the central line of the magnetic core onto the circuit board intersects the outer periphery of the circuit board is defined as Y, the antenna coil satisfies Y≧X≧0.8Y.

摘要： A highly sensitive magnetic antenna and an antenna device achieve strong coupling with magnetic flux substantially perpendicular to main surfaces of a magnetic core, an enlarged antenna opening, and increased efficiency of magnetic flux radiation. The magnetic antenna includes a flexible substrate and a magnetic core preferably having a substantially rectangular plate shape. The flexible substrate has a spiral coil conductor located thereon, and the coil conductor has a conductor opening located at the center of the winding center thereof. The flexible substrate is bent in the vicinity of the two sides of the coil conductor spaced apart from the center of the conductor opening and along the two sides of the magnetic core, so as to wrap around the upper surface, left and right surfaces, and portions of the lower surface of the magnetic core.
