提出了一种适用于Ka波段的基于液晶的连续电调谐复合左右手漏波天线。该天线具有一维波束转向能力，用于固定的操作频率。模拟，矢量网络分析，和远场测量的一个建成的原型在这项工作中连同详细的制造过程。LC分子的取向通过施加0 V至60 V之间的调谐电压来完成，这导致在26.7GHz的固定操作频率下相对于宽边从-5度至+9度的光束转向范围。
A continuously electrically tunable composite right/left-handed leaky-wave antenna based on liquid crystal is presented for Ka-band applications. The antenna features one dimensional beam steering capabilities for a fixed operation frequency. Simulations, vectorial network analysis, and far field measurements of a built prototype are presented in this work together with the detailed fabrication process. Orientation of the LC molecules is done applying a tuning voltage between 0 V and 60 V that leads to a beam steering range from -5 to +9 degrees with respect to broadside at a fixed operation frequency of 26.7 GHz.
