| Research Abstract |
Millimeter wave (MMW) liquid crystal phase shifter is investigated focusing on the advantage of integration easiness in the coplanar waveguide (CPW), which is well known as an excellent planar type of circuit for the super high frequency electro-magnetic waves. It is empirically confirmed that the liquid crystal (LC) material integration phase shifter can easily be obtained by introducing a sandwich cell structure which is commonly used in many LC device applications. After the optimization of upper electrode structure, dielectric substrate and so on, the phase shifting properties are improved up to about 50GHz.
