基于阵列天线依靠阵元间电磁耦合拓展带宽的理论,提出阵元调流电感加载技术,设计一种新型超宽带相控阵天线。相比于一般紧耦合阵列天线,将工作带宽从5 倍频程提高至8. 8 倍频程。通过对天线进行加工与测试,验证其具备良好的波束特性和较高的辐射效率。其结果是该阵列天线可广泛应用于具备侦察、干扰、探测、通信等多功能电子系统。

Based on the theory that the array antenna expands its bandwidth by electromagnetic coupling between array elements, a novel ultra-wideband (UWB) phased array antenna is designed by using the current-regulating inductance loading technology of array elements. Compared with the general UWB array antenna, the operating bandwidth is increased from 5:1 to 8. 8:1, and grateless scanning in passband is realized. The antenna is processed and measured to verify its good beam characteristics and high radiation efficiency. Therefore, the array antenna can be widely applied to multifunctional electronics systems with reconnaissance, interference, detection, communication and other functions.
