PROBLEM TO BE SOLVED: To provide a space-saving antenna device of low manufacturing cost, capable of exhibiting high receiving sensitivity performance, using an integrated antenna configured of same antennas conforming to a plurality of radio communication methods.SOLUTION: An antenna device 10 includes: a first conductor element 1 having a perturbation portion 2 of which mutually opposite two corners are notched; a second conductor element 5 disposed on the identical plane to the first conductor element 1 in a manner to enclose the first conductor element 1 with a predetermined gap G; a third conductor element 8 formed on the identical plane to the first and second conductor elements 1, 5, and disposed with a predetermined gap W from the second conductor element 5; a first power supply terminal 3; and second power supply terminals 6, 7. As a first antenna, it is operated with the first conductor element 1 as a radiation element and the second conductor element 5 as a ground conductor. Also, as a second antenna, the second conductor element 5 and the third conductor element 8 are operated as a dipole element. |
