PORTABLE COMMUNICATION TERMINAL

PROBLEM TO BE SOLVED: To improve the speech quality of a cellular phone by widening the angle of directivity of an antenna device. SOLUTION: A first coil 1 is connected to a linear antenna element 2 having a second coil 3 at its tip and to a power supply part 8. Further, a planar antenna element 10 is provided in a direction orthogonal to the linear antenna element 2 so as to surround a multidirectional switch 6, the left function key 12 and the right function key 13 of a cellular phone. An extender 15 extending from the left function key 12 side is provided so as to overlap the coil 1 in order to electromagnetically couple the coil 1 with the planar antenna element 10. In transmission, a high-frequency power is branched by the first coil 1 into the two antenna elements 2, 10, and in reception, the reception radio waves of the two antenna elements 2, 10 are combined in the first coil 1. Thus, the angle of the directivity can be widened compared to a conventional antenna. COPYRIGHT: (C)2006,JPO&NCIPI
