<P>PROBLEM TO BE SOLVED: To reduce the size of a multifrequency sharing antenna. <P>SOLUTION: A multifrequency sharing antenna including multiple antenna elements, which respectively resonate at different frequencies, includes dipole elements 12, 13 and a loop-like antenna element 11 as the multiple antenna elements. The loop-like antenna 11, from among the multiple antenna elements, resonates at at least the lowest frequency. The dipole elements 12, 13 are disposed on the outer peripheral side of the loop-like antenna 11 and are not disposed on the inner peripheral side of the loop-like antenna 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
