摘要

设计了一种实用的低轮廓宽带双极化贴片子阵列，用于小卫星上的高集成x波段SAR有效载荷，具有增强隔离、抑制交叉极化和降低旁瓣电平的特点。所提出的子阵列重量轻，外形低(由于其多层PCB工艺实现的瓦片结构)。所提出的子阵列具有14db工作带宽为0.7 GHz的H-和V-pol辐射，隔离度高于40 dB。实现了15dbi的增益。副瓣电平低于- 20db。在孔视最大增益方向，交叉极化比小于-40 dB。

Design of low-profile broadband dual-polarized integrated patch sub-array for X-band SAR payload on small satellite

A practical low-profile broadband dual-polarized patch sub-array is designed for highly integrated X-band SAR payload on small satellite with enhanced isolation, suppressed cross-polarization and reduced side-lobe level. The proposed sub-array is lightweight with low profile (due to its tile structure realized by multi-layer PCB process). The proposed sub-array has 14-dB operating bandwidths of 0.7 GHz for both H- and V-pol radiations with isolation above 40 dB. It achieves the realized gain of 15 dBi. The side lobe levels are below -20 dB. The cross-to-co polarization ratios are lower than -40 dB at the bore-sight maximum-gain direction.
