We investigate liquid crystals to be suitable for a reflective antenna. The method for evaluation of liquid crystals in gigahertz is presented. Low loss tangent reaching closely to 0.01 and short decay time in switching response were achieved simultaneously by introducing compounds having para-terphenyl group without polar groups.
