PURPOSE:To increase the antenna effective diameter by distributing element antennas even at inapplicable places and feeding these antennas from active modules set at places where the element antennas are thinned. CONSTITUTION:Active modules b1-bn are connected to element antennas a1- an respectively. A phase shifter is provided together with a high output amplifier, a low noise amplifier and a transmission/reception switch. The signals given from a transmitter (e) are distributed to modules b1-bn by a power distribution synthesizer (c) via a duplexer (d). The synthesizer (c) supplies and synthesizes the reception signals of antennas a1-an via modules b1-bn. Then active modules B1-BN set at the positions of antenna elements performing no transmission/reception are used to feed element antennas A1-AN set at the positions where the physical distribution of active modules is impossible. |
