我们提出了一种共形和轻量化的天线技术的基础上E-纺织导体和聚合物陶瓷复合材料。所提出的技术的独特优点是其结构完整性，重量轻，并符合平台。电子织物导体是由单壁碳纳米管（SWNT）和Ag涂层织物制成的。由于它们的机械相容性，它们与聚合物复合材料表现出良好的结构完整性。类似地，聚合物复合材料表现出上级RF性能，介电常数范围为3至13。详细介绍了E-纺织导体的制备工艺以及与聚合物复合材料的集成工艺。我们还证明了所提出的技术与一个简单的贴片天线，其辐射性能进行测量时，它是平坦的，并符合一个圆柱形表面的优点。我们比较了它的性能与一个理想的补丁。实验结果表明，基于该技术的贴片天线的增益达到了6dB，比相同尺寸的理想无损材料贴片低2dB。当它是符合一个圆柱形表面，我们实现了2.5 dB的增益比PEC表面实现的天线。这清楚地验证了所提出的基于非传统材料的共形天线技术的优点。
We present a conformal and lightweight antenna technology based on E-textile conductors and polymer-ceramic composites. Unique advantages of the proposed technology are its structural integrity, light weight and conformity to the platform. E-textile conductors are fabricated with single wall carbon nanotube (SWNT) and Ag coated textiles. They demonstrate good structural integrity with polymer composites due to their mechanical compatibility. Similarly, polymer composites demonstrate superior RF performance with permittivity ranging from 3 to 13. Fabrication process for E-textile conductors and integration process with polymer composites is described in detail. We also demonstrated merit of the proposed technology with a simple patch antenna whose radiation performance is measured when it was flat and conformed onto a cylindrical surface. We compared its performance with that of an ideal patch. Experiments suggested that the sample patch antenna based on the proposed technique achieved 6 dB gain, which is 2 dB below a patch which has the same dimensions and made of ideal lossless materials. When it is conformed onto a cylindrical surface, we achieved 2.5 dB less gain than that of antenna realized with a PEC surface. This clearly validates the merit of the proposed conformal antenna technique based on non-traditional materials.
