摘要

提出了一种基于液晶的连续电可调谐左/右复合漏波天线。在26.7 GHz的固定工作频率下，通过施加0 V和120 V之间的调谐电压，可以实现相对于宽侧-6°到9°的波束转向。详细分析了这种特殊应用的远场测量和液晶响应时间。

Dynamic beam steering properties of an electrically tuned liquid crystal based CRLH leaky wave antenna

A continuously electrically tunable composite right/left-handed leaky-wave antenna based on liquid crystal is presented. Beam steering from -6° to 9° with respect to the broadside at a fixed operation frequency of 26.7 GHz is achieved by applying a tuning voltage between 0 V and 120 V. Far field measurements and the response times of the liquid crystal for this specific application are analyzed in detail.
