Planar type of liquid crystal (LC) cell is prepared using a coplanar waveguide (CPW) and ITO glass substrate for electronically tunable phase shifter in the ultrahigh frequency region. Since the sandwich cell structure of this device is almost the same with the conventional LC cell such as LC displays, it is easy to adopt the conventional LCD technology for the device fabrication. LC molecules in the device can be driven by only applying the voltage on the CPW electrode due to the ITO film as a floating electrode. Their transmission properties up to 65GHz are measured and also transmission change by applying the voltage is investigated for various LC materials.
