Abstract
This disclosure provides an antenna device and a mobile terminal equipped with the antenna device. The antenna device includes a coil conductor spirally wound to have a conductor opening portion at the center of winding and is formed on a flexible substrate. A magnetic sheet is disposed near, or proximal to the flexible substrate and between the coil conductor and a flat conductor of a circuit board. A side of the antenna coil that is near an edge of the flat conductor is bent toward the circuit board.
Claims18
An antenna device comprising:
- an antenna coil, a flat conductor that is disposed near the antenna coil and a casing, the antenna coil including a flexible substrate on which a coil conductor is formed and a magnetic sheet provided in contact with or proximal to the flexible substrate, wherein the flexible substrate is provided on only one side of the magnetic sheet,
- wherein the coil conductor is spirally wound and has a conductor opening portion at the center of winding,
- wherein the antenna coil is disposed near an end portion of the casing,
- wherein the magnetic sheet is provided between the coil conductor and the flat conductor, and
- wherein the direction from a first conductor portion of the coil conductor that is closer to the center portion of the flat conductor to a second conductor portion of the coil conductor that is closer to an edge of the flat conductor bends toward the flat conductor.
