波导裂缝阵列天线具有效率高、口面分布可以独立控制、结构紧凑、加工和安装简单等优点。尤其是配以数字式移相器时,可以实现一维波束电扫,这在对空与对海面搜索、战场前沿侦察等应用方面是有用的。本文介绍一个实例,并给出完整实验结果。可以看出,在预定频率和扫描角范围内,天线波束没有出现大的畸变,不同切割平面上方向图的性能也很好,正交极化电平得到很好的抑制。 Waveguide slot array antenna with high efficiency, oral distribution can be controlled independently, compact structure, processing and installation is simple and so on. Especially with the digital phase shifter, you can achieve one-dimensional beam sweep, which is useful in applications such as air and sea search, battlefield detection and other applications. This article presents an example, and gives the complete experimental results. It can be seen that there is no large distortion of the antenna beam within the predetermined frequency and scanning angle range, the performance of the directional pattern on different cutting planes is also good, and the orthogonal polarization level is well suppressed.
