phased-array antennaの例文

• Floquet ports : these periodic ports enable designers of phased - array antennas and frequency - selective surfaces to obtain separate fields into modes for better understanding and examine phase information for each mode
• With compensation of signal ’ s time delay from different radiating element by phase shifters , phased - array antenna can control array beam easily . because there are no mechanical devices for rotating beam , the phased - array antenna system can scan everywhere in beam covered areas in millisecand by stepping the phase shifters . it improves the tracking velocity of antenna towards the object , and becomes the development trends of weapon system antennas
