Abstract

Recent developments in wearable wireless communication systems have significantly increased the demand for stretchable antennas. The substrate, which is a critical component for antennas, has a great impact on the antenna’s electromagnetic performance and mechanical properties, particularly at millimeter-wave frequencies. However, conventional methods of incorporating low-loss ceramics into stretchable polymers cannot achieve an equilibrium between low dielectric loss and optimal stretchability. To resolve this issue, we present a novel approach that synergistically integrates electrospun barium titanate (BaTiO₃) nanofibers with poly(dimethylsiloxane) (PDMS), achieving a composite membrane substrate with ultralow dielectric loss and exceptional stretchability. Based on this advanced substrate, we develop a wearable array antenna that demonstrates stretchability and remarkable radiation characteristics, effectively addressing the constraints associated with conventional PDMS-based antennas. This proposed antenna is expected to be an excellent candidate for next-generation wearable and stretchable millimeter-wave 5G wireless communication.

基于电纺batio3 /PDMS复合膜衬底的高增益毫米波可拉伸阵列天线

可穿戴无线通信系统的最新发展显著增加了对可伸缩天线的需求。衬底是天线的关键部件，对天线的电磁性能和机械性能有很大的影响，特别是在毫米波频率下。然而，传统的将低损耗陶瓷掺入可拉伸聚合物的方法无法在低介电损耗和最佳拉伸性能之间达到平衡。为了解决这个问题，我们提出了一种新的方法，将电纺丝钛酸钡（BaTiO3）纳米纤维与聚二甲基硅氧烷（PDMS）协同集成，实现了具有超低介电损耗和优异拉伸性的复合膜衬底。基于这种先进的衬底，我们开发了一种可穿戴阵列天线，该天线具有可拉伸性和显著的辐射特性，有效地解决了传统pdm天线的相关限制。该天线有望成为下一代可穿戴和可拉伸毫米波5G无线通信的优秀候选者。
