摘要

Variable ferroelectric delay line technology has been utilized to implement a proof-of-concept, continuous scanning, ferroelectric integrated phased array antenna system. S/sub 21/ phase shifts of up to 157/spl deg/ have been achieved from the phase shifter itself via analogous variation of a DC bias. When integrated into a phased array, beam scanning of at least /spl plusmn/12/spl deg/ is achieved prior to any optimization. Some of the key material requirements, fabrication procedures, characterization, and assembly of the ferroelectric material are revealed. The design, integration, and performance of the array system using such phased shifters are presented.
