| Zusammenfassung: | An antenna device capable of securing the space for disposing a conductor element easily in view of the trend of downsizing, without the need of a step for the conductance with other electric devices. An antenna feeder part comes in contact with a feeding spring at the time of contraction so that a helical part can function as an antenna as well as a conductor element is provided elongating along an antenna storage part in the space in the housing for capacitive coupling with the antenna feeder part so that the antenna gain is improved by the conductor element. Therefore, even when the radiation of the helical part is restrained by the influence of a human head part, in particular, of an earlobe, since the conductor element is the radiation source, it is easy to secure the space as well as a step for the conductance with other electric devices is not required, and restraint of the radiation by the human head part can be alleviated for the antenna device as a whole so that the antenna gain can be improved. |
