Abstract

PURPOSE:To realize a microminiature antenna of 4 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 and thus decreasing the length of the antenna element. CONSTITUTION:Antenna device 49 consists of antenna element constitution part 50 including 4 pieces of dipole antennas and the signal compounding and others, switching control part 51 including the switching control means and the signal compounding unit, and others. On the other hand, memory part 56 stores the channel selection control code of receiver 53 and the direction switching code of the optimum antenna in combination. And now if the channel selection control code is set through the channel selecting operation at channel selection control part 54, memory control part 58 transfers continuously the transfer instruction signal until the coincidence is obtained by code comparator 55 between the set channel selection control code and the channel selection code in memory part 56. And when the coincidence is obtained between the both codes, the transfer action is discontinued. Then both the channel selection code and the direction switching control code of the antenna are delivered to output terminals 57c and 57d each to be then applied to receiver 53 and control part 51 respectively. As a result, both the channel selection and the antenna's optimum directivity can be obtained simultaneously and electronically.
