<P>PROBLEM TO BE SOLVED: To provide an antenna device which enables three resonance frequencies (a first to a third frequency) to be adjusted independently. <P>SOLUTION: According to an embodiment, an antenna device comprises: a first linear antenna element; a second linear antenna element; and a third linear antenna element. One end of the first antenna element is connected to a feeding point. The second antenna element has the element length shorter than the first antenna element, and one end of the second antenna element is connected to the feeding point. The third antenna element has the element length shorter than the first antenna element, and one end of the third antenna element is connected on the first antenna element. <P>COPYRIGHT: (C)2012,JPO&INPIT |
