Abstract

PURPOSE:To keep an output of an antenna system to a constant value and to increase the reliability, by increasing an output level of an output amplifier of other antenna elements when an output of a part of antenna elements of a phase synthesis antenna is interrupted. CONSTITUTION:A high freqnency input is inputted to an output signal distribution circuit 3 from a terminal 10 for N distribution and applied to antenna elements 31-34 through variable phase shifters 11-14 and output amplifiers 21-24 respectively. The output amplifiers 21-24 provides power supply circuits 51-54. A phase control circuit 2 controls the variable phase chifters 11-14 to control antenna beam. An RF output control circuit 3 instructs a power supply circuit of other signal system to increase the collector voltage of an output amplifier, when an output of any signal system is interrupted, and the performance of overall antenna system can be assured by increasing the output of the output amplifier of the rest signal system.
