Abstract

PURPOSE:To ensure the free control of the directional characteristics by giving the control to the variable phase shifters provided to a pair of abbreviated dipole antennas possessing the distribution constant inductance each. CONSTITUTION:Folded-type dipole antennas 8 and 9 possessing the distribution constant inductance each are distributed to oppose each other with a fixed distance secured between and also connected to signal compounding unit 10. And variable phase shifters 13 and 14 provided to antennas 8 and 9 each are controlled by control meand 15. Here the control signal of meand 15 is varied to give the control to the extent of phase shift of shifters 13 and 14 respectively. As a result, the directional characteristics can be controlled freely. In such way, a small-sized antenna device can be obtained with the free control secured for the directional characteristics.
