摘要

提出了一种利用块状铁电材料进行光束扫描的新方法。通过类似的直流偏置变化，移相器可以实现高达148/spl°/的相移。当集成到相控阵中时，在进行任何优化之前，至少可以实现/spl plusmn/12/spl度的波束扫描。

Characterization and application of ferroelectric phase shifters for phased array scanning [BST ceramics]

A novel beam scanning method utilizing bulk ferroelectric materials is presented. S21 phase shifts of up to 148/spl deg/ could be achieved from the phase shifter 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.
