Keating & Bennett, LLP
Antenna apparatus and communication terminal
An antenna apparatus includes a power supply coil, a booster electrode sheet, a magnetic sheet, and a ground substrate arranged in this order from the top. The power supply coil includes a spiral coil conductor located on a flexible substrate. The booster electrode sheet includes a booster electrode located on an insulating substrate. The booster electrode includes a conductor region covering the coil conductor, a conductor aperture covering a coil window, and a slit portion connecting the outer edge of the conductor region and the conductor aperture in plan view. The magnetic sheet covers the booster electrode sheet so that the magnetic sheet covers a region slightly larger than a region including the conductor aperture and the slit portion of the booster electrode.
