| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an antenna device that is small enough to have it contained in a mobile communication device, that is able to receive a signal of FM radio broadcast, and that reduces an impact of noise without installing a metal shielding member and the like.SOLUTION: An antenna device comprises: a chip antenna provided with a first radiation electrode; a power supply terminal to the first radiation electrode; and a support member provided with a second radiation electrode. On the support member, the chip antenna is mounted such that the chip antenna overlaps with the second radiation electrode with space in between. The first radiation electrode of the chip antenna is formed in a coil shape, the second radiation electrode of the support member is formed in a linear shape, one end of the first radiation electrode is connected with the power supply terminal, the other end is connected with one end of the second radiation electrode, and the second radiation electrode is placed farther from a circuit board on which the support member is mounted than the first radiation electrode. |
