Abstract
PURPOSE:To reduce the wt. of an antenna part, by a method wherein a receiving module is provided to the antenna part and made active at the time of reception but passive at the time of transmission. CONSTITUTION:The transmission power from a transmitter 5 is distributed to a large number of transfer devices 7 through a duplexer 2 and a power distributor-synthesizer 4 and passes through two duplexers 2 to be emitted to a space from an element antennae 1. The receiving signal entering from the antennae 1 enters active receiving modules 3 through the duplexers 2. Herein, receiving powers are amplified in low noise and synthesized through the duplexers 2, the transfer devices 7 and the synthesizer 4 to enter a receiver 6 through the duplexer 2. As mentioned above, since the modules 3 are provided to the antenna part and made active at the time of reception and made passive at the time of transmission, the antenna part can be miniaturized and reduced in its wt. by the wt. for a transmission module.
