本文研究了一种新型的部分填充液晶的传输线拓扑结构作为高性能连续可调移相器的可行性。首先简要介绍了液晶的特殊性质。然后，理论结果的基础上开发的仿真工具进行了讨论，以解释这种波导结构相比，其他技术的优势。实验结果证实了预期的性能，在Ka波段区域显示出良好的品质因数。
In this paper a novel transmission line topology partially filled with liquid crystal is investigated in terms of its usability as a high performance continuously tunable phase shifter. At first the special properties of liquid crystals are described briefly. Then theoretical results based on a developed simulation tool are discussed in order to explain the advantages of this waveguide structure compared to other techniques. Experimental results confirm the expected performance by showing an excellent Figure-of-Merit in the Ka-band region.
