<p><P>PROBLEM TO BE SOLVED: To provide a walkie-talkie which prevents degradation of the frequency characteristics of the impedance and the antenna characteristics, and has the antenna element built-in so as to maintain compact size. <P>SOLUTION: The walkie-talkie 1 is provided with a first circuit board 5, a second circuit board 6 connected electrically with the first circuit board, a first case 2 for housing the first circuit board, a second case 3 which houses the second circuit board and is linked with the first case, the antenna element 7 which the first case has incorporated within, and a feeding portion arranged on the first circuit board and connected electrically to the antenna element. The first circuit board has a non-grounded region formed in an edge region on the second case side, and a grounded region other than the ungrounded region. The feed portion is arranged in the ungrounded region of the first circuit board, and 80% or more of the total length of the antenna element will not exist on the first circuit board. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
