PROBLEM TO BE SOLVED: To provide an antenna for dual band which allows for further compaction of a terminal.SOLUTION: The antenna comprises: an antenna body; a stationary portion including a cavity having an opening in which a substrate is placed; and a connection for connecting the stationary portion and the antenna body. On one side of the substrate, a circuit placed in the cavity while being connected electrically with the antenna body and including a parallel circuit of a coil and a capacitor is arranged, and an electrode being connected with the circuit is arranged on the other side of the substrate. The coil interrupts a high frequency current of first frequency band, being supplied to the electrode, to be supplied to the antenna body, and supplies a high frequency current of second frequency band lower than the first frequency band from the electrode to the antenna body. The capacitor supplies a high frequency current of first frequency band from the electrode to the antenna body, and interrupts a high frequency current of second frequency band to be supplied from the electrode to the antenna body. |
