Nematic liquid crystals (LC) offer the capability to electronically reconfigure their dielectric permittivity tensor by applying a low AC voltage. This feature can find pertinent applications in submm-wave antenna technology in developing reconfigurable devices. In this contribution we review recent developments for the dielectric characterization of nematic liquid crystal samples at mm wavelengths and describe their applications in reconfigurable reflectarray antenna and tunable linear to circular polarization reflectors. The paper describes the theoretical aspects which underpin the technology that is employed for the realization, packaging and testing.
