Due to the multiple dimensional and embeddable characterizations, the three-dimensional woven structure is of great potential as a platform for multifunctional composites. As an example of this concept, we proposed a light-weight and high-gain three-dimensional woven spacer microstrip antenna (3DWS-MA) for the first time by integrating microstrip antenna into 3D woven spacer composites. The single-element 3DWS-MA showed superb electromagnetic performance with the gain value of 7.1 dB, which is more than four orders of magnitude higher than traditional microstrip antenna (2.5 dB). Furthermore, the 3DWS-MA maintained proper resonant frequency and impedance matching after the impact of 18 J, exhibiting excellent structural integrity.

由于具有多维和可嵌入的特征，三维编织结构作为多功能复合材料的平台具有巨大的潜力。作为该概念的一个示例，我们首次通过将微带天线集成到3D编织间隔物复合材料中，首次提出了轻巧，高增益的三维编织间隔物微带天线（3DWS-MA）。单元素3DWS-MA表现出了出色的电磁性能，增益值为7.1 dB，比传统的微带天线（2.5 dB）高出四个数量级。此外，3DWS-MA在18 J的冲击后仍保持适当的谐振频率和阻抗匹配，表现出出色的结构完整性。
