摘要： PROBLEM TO BE SOLVED: To provide a communication device which prevents a handset from being detuned and reduces an effect caused by a ground plane so as not to fluctuate performance properties of an antenna. SOLUTION: A handset comprises first and second enclosures pivotally joined to permit the rotation of one enclosure relative to the other enclosure. An embedded antenna 78 is disposed in an upper part of the ground plane formed in a printed circuit board 156 in the first enclosure. The second enclosure also includes a ground plane. A feed terminal 80 and a ground terminal 82 which are formed on the printed circuit board 156 are joined to meanderline conductors 84, 86, and further, a feed terminal 88 and a ground terminal on a radiating element 79 of the embedded antenna 78 are connected to limit field coupling between the ground plane and the feed terminal in the second enclosure, thereby reducing detuning.
