Apparatus and method for a communication device

A method of manufacturing a communication device comprising an antenna coil, a sender/receiver circuit, a memory circuit, and a control circuit for non-contact electromagnetic wave communication with an interior of the communication device by using the antenna coil, the method comprising:

• forming the antenna coil into a flat concentric disk shape,
• housing the antenna coil, the sender/receiver circuit, the memory circuit, and the control circuit inside a non-conductive sealed container,
• plurally arranging the sealed container in a prescribed interval along a longitudinal direction of a thin long primary sheet material, and
• plurally arranging a sheet-like magnetic material with a high magnetic permeability in a prescribed interval along a longitudinal direction of a thin long secondary sheet material,
• wherein each container body and each sheet-like magnetic material are postionally adjusted relative to each other, in which the sheet-like magnetic materials is positionally adjusted to be arranged on one side of the antenna coil extending along the antenna coil from an intermediary portion between a diametral center of the antenna coil and an inner peripheral side to an outer area of one of the sides of the antenna coil in a case where the antenna coil has a concentric disk shape
• wherein the primary sheet material and the secondary sheet material are joined to each other, and
• wherein each combined body of the container body and the sheet-like magnetic material is divided.

A method of communication with a communication device comprising an antenna coil, a sender/receiver circuit, a memory circuit, and a control circuit for non-contact electromagnetic wave communication with an exterior of the communication device by using the antenna coil, the method comprising:

• forming the antenna coil into a flat concentric disk shape;
• and
• arranging the antenna coil between a primary sheet-like magnetic material with a high specific magnetic permeability and a secondary sheet-like magnetic material with a high specific magnetic permeability,
• wherein the primary sheet-like magnetic material and the secondary sheet-like magnetic material are extended along the antenna coil from a center portion of the antenna coil to an outer area in opposite directions relative to each other,
• wherein the primary sheet-like magnetic material and the secondary sheet-like magnetic material are arranged overlapping each other at a center portion of the antenna coil, and
• wherein non-contact electromagnetic wave communication with the external is performed in a state where directivity of the antenna coil is heightened by the sheet-like magnetic material.
