Disclosed is an antenna capable of use in a broad frequency range and capable of freely adjusting the level of the frequency band used. An antenna (10A) is provided with a resonator conductor tube (12) positioned outside of and covering a feeder unit (18) of an unbalanced feed member (11), a ground conductor tube (13) positioned outside of and covering a non-feeder unit (19) of the unbalanced feed member (11), and a connector conductor guide (14) disposed between said conductor tubes (12, 13) and the unbalanced feed member (11). In the antenna (10A), said conductor tubes (12, 13) and the unbalanced feeding member (11) are electrically fixed to the connector conductor guide (14) via a fixing means, and the feeding unit (18) of the unbalanced feed member (11) has an exposed portion (20) extending a prescribed amount from and uncovered by the resonator conductor tube (12) in the length direction thereof. |
