<p>PURPOSE:To obtain a phased array antenna in which retrieval, capture and tracking performance is improved without increase of the hardware. CONSTITUTION:Plural low frequency antenna elements 10 and plural high frequency antenna elements 20 are arranged in overlapping with each other. The plural low frequency antenna elements 10, a tri-plate type distribution synthesizer 70, a transmission reception module 130 for low frequency connecting to the synthesizer 70 also for implementing amplification and phase adjustment form a low frequency phased array antenna. The plural high frequency antenna elements 20, plural high frequency use transmission reception modules 90 connected individually and a high frequency transmission line 80 connecting to the modules 90 also through which a control signal, a power supply, an exciting signal and a reception signal are sent form the high frequency phased array antenna.</p> |
