Abstract

PURPOSE:To decrease the length of the antenna element and thus realize a microminiature antenna of 6 elements with a high working gain, by securing the interlocking between the directivity switching of the antenna device and the channel selection switching of the receiver connected to the antenna device. CONSTITUTION:Antenna device 45 consists antenna element constitution part 46 including of 6 pieces of dipole antennas and the signal compounding unit, switching control part 47 including the switching control means and the signal compounding unit, and others. On the other hand, memory part 52 stores the channel selection control code of receiver 49 and the optimum antenna's direction switching code in combination. Now if the channel selection control code is set through the channel selecting operation at channel selection part 50, memory control part 54 transfers continuously the transfer instruction signal until the coincidence is obtained at code comparator 51 between the set channel selection control code and the channel selection code in memory 52. And when the coincidence is obtained between the both codes, the transfer is discontinued. And both the channel selection code and the direction switching control code of the antenna are delivered to output terminals 53c and 53d each to be then applied to receiver 49 and part 47. As a result, the optimum directivity can be obtained electronically and at one time for both the channel selection and the antenna.
