Title:
MOBILE PHONE
Document Type and Number:
Japanese Patent JP2007306287
Kind Code:
A
Abstract:

To provide a mobile phone which is enabled to stably communicate by suppressing mutual interference between an antenna for mobile phone communication and an antenna for RFID, decreased in number of components and assembly man-hour, and improved in antenna characteristic.

Two antennas which are the antenna 12 for mobile phone communication and the antenna 11 for RFID are formed not individually, but together on one flexible printed board 1. Consequently, the gap between the two antennas can be held constant and the number of components does not increase, so the production cost and the component cost can be reduced. The flexible printed board 1 can optionally be curved, so the antenna area is made large to have sufficient gains of the antennas, and an electromagnetic wave shield sheet is arranged on the internal surface side of the flexible printed board 1 to suppress influence of a circuit board such as a mother board nearby an antenna (particularly, the antenna 11 for RFID).
