Title: Receiving device
Inventor: KANE JIYOUJI
IPC: H01Q3/24
Filed: 1979-07-09
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:The control signal gives the control to each variable reactance of folded and abbreviated dipole antennas 31-36 possessing the distribution constant inductance. These control signals are applied from control means 40 and via switching means 42. And antennas 31 and 34 which also function as the radiators are connected to compounding unit 37 via switching means 43.
