<P>PROBLEM TO BE SOLVED: To make an antenna device into a multi-band and low SAR by simple structure. <P>SOLUTION: The antenna device is provided with: a metal rotation hinge 108; a feeding part 401; a filter circuit 402; a radiation element 403; and a metal spring 501. Here, the filer circuit 402 is constituted so as to shield current with a frequency f1 and to pass current with a frequency f2. The antenna device is made into the multi-band by using the metal rotation hinge 108 and the metal spring 501 as an antenna element in the frequency f1, and using the metal rotation hinge 108, the metal spring 501, the filter circuit 402, and the radiation element 403 as the antenna element in the frequency f2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
