摘要/Abstract

摘要： 为研究宽频透波3D打印氮化硅天线罩多孔微结构,利用SLA光固化3D打印技术制备了氮化硅测试试样,对其电磁性能进行了测试.利用计算模拟方法,设计并研究了Ku(12~18 GHz)及Ka(27~40 GHz)波段不同厚度氮化硅实体结构、蜂窝结构以及梯度蜂窝结构的电磁性能.结果表明:厚度与微结构设计显著影响氮化硅材料电磁性能.蜂窝氮化硅多孔结构使透波率得以显著改善.在进行梯度设计后,梯度蜂窝氮化硅多孔结构能减小电磁波在界面处的反射,并实现结构的阻抗梯度渐变,其在Ku(12~18 GHz)及Ka(27~40 GHz)波段的透波率均达到80%以上,且在全波段具有极低(低于3%)的能量损耗率.

Abstract: To investigate wideband transparent 3D-printed Si₃N₄ antenna enclosures, this study employed Stereolithography (SLA) 3D printing technology to fabricate Si₃N₄ samples and conducted electromagnetic performance testing. Computational simulations were then utilized to evaluate the electromagnetic performance of solid structures, honeycomb structures, and gradient honeycomb structures of Si₃N₄ with varying thicknesses in the Ku(12~18 GHz) and Ka(27~40 GHz) frequency bands. The results revealed that thickness and microstructure design significantly influence the electromagnetic properties of Si₃N₄materials,and the transmittance of the honeycomb Si₃N₄ porous structure was significantly enhanced. Furthermore, by implementing a gradient design, the gradient honeycomb Si₃N₄ porous structure reduced the reflection of electromagnetic waves at the interface, achieving a gradual transition of impedance. Its transmittance exceeded 80% in the Ku(12~18 GHz) and Ka(27~40 GHz) frequency bands, with an extremely low energy loss rate (below 3%) across the entire frequency range.
