<p><P>PROBLEM TO BE SOLVED: To improve the radiation efficiency of an antenna at the time of closing enclosures of a wireless device constituted by connecting two or more enclosures so that they can be opened and closed. <P>SOLUTION: An antenna 17 is connected to a first substrate 13 incorporated in one enclosure of the wireless device, through a feed point 16. A magnetic material layer 18 is disposed between the first substrate 13 and a second substrate 14 incorporated in the other enclosure. The first substrate 13, the second substrate 14, and the magnetic material layer 18 are of approximately the same shape and size, and the magnetic material layer 18 is placed in an approximately parallel state between the first substrate 13 and the second substrate 14. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
