本文提出了一种新型的K波段紧凑型频率控制波束控制阵列，它采用固定的渐进延迟线和集成准八木天线单元的无源双平衡MMIC混频器。通过简单地同时改变LO和IF信号的频率来执行波束转向，使得辐射频率保持恒定。在氧化铝衬底上制作的K波段（20 GHz）四元件阵列演示了40度扫描，LO频率从22到26.2 GHz的变化，通过安装在LO线中的短延迟线，并确保宽带数据传输与定义良好的辐射模式。
A new type of compact K-band frequency-controlled beam-steering array utilizing fixed progressive delay lines in combination with passive double-balanced MMIC mixers integrated with quasi-Yagi antenna elements is presented. The beam steering is carried out by simply changing the frequency of the LO and IF signals at the same time such that the radiation frequency keeps constant. The K-band (20 GHz) four-element array fabricated on the Alumina substrate demonstrates 40 degree scanning with an LO frequency change from 22 to 26.2 GHz by the short delay lines installed in the LO line and ensures broadband data transmission with well-defined radiation patterns.
