In this paper, we investigated dielectric characteristics within millimeter-wave band of structurally-modified liquid crystal molecules based on free space method for next-generation wireless communication system. As the results, we clarified that liquid crystal molecule having rigid groups and strong interaction among molecules has reduction of dielectric loss value.
