Abstract

With the continuous development of radar, higher and higher demands are placed on the antenna. The traditional single-band antenna can obtain limited information, and the use of dual-band antenna can expand the dimension of target information acquisition, and more effectively classify and identify various targets. Therefore, in this paper, the Ka/X double-segment phased array antenna is researched, and a phased array antenna that can work in the Ka and X frequency bands is designed by HFSS simulation. The Ka and X frequency bands are combined in the form of a layered microstrip antenna. The designed dual-band antenna has a large bandwidth of 6GHz in the Ka frequency band, the gain reaches 29dB, and the standing wave is less than 2. It can achieve ±25 degree scanning function, and has good electrical properties. The designed dual-band antenna has a bandwidth of 700MHz in the X-band, the gain reaches 18dB, and the standing wave of less than 2. It can achieve ±30 degree scanning function and has good electrical performance. The Ka/X double-segment phased array antenna design has laid a foundation for the Ka/X double-segmented phased array antenna research, which has important practical significance.

Ka和X双频微带相控阵天线设计

随着雷达的不断发展，对天线提出了越来越高的要求。传统的单波段天线只能获得有限的信息，而双频天线的使用可以扩大目标信息获取的维度，更有效地对各种目标进行分类和识别。因此，本文对Ka/X双段相控阵天线进行了研究，并通过HFSS仿真设计了一种能够在Ka和X频段工作的相控阵天线。Ka和X频段以层状微带天线的形式组合。所设计的双频天线在Ka频段具有6GHz的大带宽，增益达到29dB，驻波小于2。可实现±25度扫描功能，具有良好的电性能。设计的双频天线在x波段的带宽为700MHz，增益达到18dB，驻波小于2。可实现±30度扫描功能，电气性能良好。Ka/X双段相控阵天线的设计为Ka/X双段相控阵天线的研究奠定了基础，具有重要的现实意义。
