Abstract:
An antenna device has semi-conductive antenna bodies each having a predetermined length, which are positioned on a dielectric substrate, and control electrodes that are respectively connected with the semi-conductive antenna bodies. Direct-current biased voltage applied across each of the control electrodes is controlled to switch each of the antenna bodies between their insulation state and their conductive state.
