<p><P>PROBLEM TO BE SOLVED: To prevent antenna characteristics from deteriorating by disposing an antenna element capable of receiving both a main polarized wave and a crossed polarized wave apart from a case ground portion. <P>SOLUTION: A second case 102 is fitted to a first case 101 with a third case 103 interposed to be folded on the first case 101 with a first hinge portion 104 as a rotation axis, and also fitted to the third case 103 to be folded on the first case 101 with a second hinge portion 105 as a rotation axis. The antenna element 112 is formed in an L shape, and disposed at a corner portion 102a most distant from the case ground portion 11 while the second case 102 is opened. An electricity feeding portion 115 is provided to a circuit board 113 to feed electricity from the tip side of a short-side portion 112a of the antenna element 112. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
