<P>PROBLEM TO BE SOLVED: To provide an antenna which attains band widening so as to be available in frequency bands over a wide range. <P>SOLUTION: An antenna 100 includes a power feeding element 110 connected to a feeding point 101 and a radiation conductor 120 connected to a grounding point 102, wherein the radiation conductor 120 is folded at 180° at a folding part 123 and includes a first conductor side 121 and a second conductor side 122. The power feeding element 110 is disposed in such a way that its length is approximately equal to that of the first conductor side 121 and the second conductor side 122 and a tripartite distance becomes approximately equal. When the power feeding element 110 is excited, the first conductor side 121 and the second conductor side 122 are excited, and a band widened characteristic of the antenna 100 is easily achieved by triple resonance overlapping resonance therebetween. <P>COPYRIGHT: (C)2009,JPO&INPIT |
