利用液晶（LC）材料制作了一种微波波段的平面型电调移相器。设计了一种基于微带线的新型平面波导结构，可以将正向微带线转换为反向微带线。新的转换电路使我们能够在微带线上引入LC材料，就像在使用共面波导型液晶移相器的情况下一样容易。在施加小于10 V的驱动电压的情况下，经验上确认了高达约10 GHz的较大相移特性。
A planar-type electrically tunable phase shifter is demonstrated in the microwave region by using liquid crystal (LC) materials. A novel planar waveguide structure based on the microstrip line, which can convert the normal microstrip line to the inverted one, is designed. The new conversion circuit enables us to introduce LC materials on the microstrip line as easily as in the case of using the coplanar waveguide type of liquid crystal phase shifters. Larger phase shifting properties are confirmed empirically up to approximately 10 GHz with the application of a driving voltage of less than 10 V.
