Abstract

PURPOSE: To simplify the whole device and to make it small in size and light in weight by constituting said device so that at least plural pieces of branching circuits to which plural pieces of antenna element have been connected are provided, and also, to each of these branching circuit, a distributing and synthesizing circuit is connected through a transmitting and receiving circuit.
CONSTITUTION: Each antenna element 1 is connected to a branching circuit 2, respectively and constitutes one antenna circuit 10. The branching circuit 2 consists of plural pieces in accordance with the number of branches, but these branching circuits can be constituted, for instance, of a 3dB Wilkinson type branching circuit. As for a transmitting and receiving circuit 3, a circulator 31 connected to an antenna circuit is connected to a high frequency transmitting/ receiving switch 34 through transmitting use/receiving use amplifying circuits 32, 33, and connected to a distributing and synthesizing circuit 4 through a phase shifter 35. A control terminal 36 receives a signal from a control circuit which is not shown in the figure in accordance with switching of transmission and reception, and controls the switch 34 and the phase shifter 35. The transmitting and receiving circuit 3 can be constituted by converting it to a module.
