Microstrip line structure has been mainly used in microwave phase shifter using liquid crystal, but there is a serious problem about the response time upon voltage removal. Polymer stabilized nematic liquid crystal, in which a mesogenic monomer is doped into a nematic liquid crystal and is polymerized in the nematic phase, shows short response time upon voltage removal even in the thick cell. In this study, we discuss the response time of microstrip-line-type microwave variable phase shifter using polymer stabilized nematic liquid crystal with thermal polymerization.
