Abstract

PURPOSE:To always ensure an automatic reception in the optimum direction by giving the electrical control to the directivity of the antenna device consisting of the dipole antennas. CONSTITUTION:Folded and abbreviated dipole antennas 31-34 possessing the distribution constant inductance are connected to compounding units 35 and 37 via phase shifters 41-44 each and then to compounding unit 39 via switching means 47. At the same time, each phase shifter is connected to control means 45, which delivers two different phase control signals, via switching means 46. The receiver connected to the antenna device having such constitution detects the extent of the multipath effect contained in the intermediate frequency signal. And the control is given to switching means 46 and 47 so that the extent of this effect may be minimum, and thus the directivity can be controlled for the antenna device. In such way, an automatic reception is always possible in the optimum direction, at the same time attaining the miniaturization of the antenna device.
