Abstract

An ultra-thin compact flexible CPW-fed slot monopole antenna suitable for the Internet of Things (IoT) applications was achieved as a result of exploring the use of Zirconia-based ENrG's Thin E-Strate for the antenna's design. The electromagnetic characterization of the novel material at the frequency range of interest was analyzed. A comparison was made concerning the required dimensions and the simulation results regarding impedance matching and radiation properties, for three different dielectric substrates: Novel flexible ceramic (ENrG's Thin E-Strate), rigid Arlon 25N, and flexible Polypropylene (PP). Two different metallization techniques-electrotextile-based and inkjet printing-were used in the fabrication of prototypes based on ENrG's Thin E-Strate. Return losses measured results for the fabricated prototypes with both procedures was compared, as well as with simulation. The best prototype on the ENrG's Thin E-Strate was compared with one on Arlon 25N, in terms of radiation properties in an anechoic chamber, and conclusions were drawn.

摘要

通过探索将基于氧化锆的ENrG薄型电子层用于天线设计，实现了一种适用于物联网（IoT）应用的超薄紧凑型柔性共面波导馈电缝隙单极天线。分析了这种新型材料在感兴趣频率范围内的电磁特性。针对三种不同的介电基板：新型柔性陶瓷（ENrG薄型电子层）、刚性Arlon 25N和柔性聚丙烯（PP），比较了所需尺寸以及关于阻抗匹配和辐射特性的模拟结果。在基于ENrG薄型电子层制造原型时，使用了两种不同的金属化技术——基于电子织物的技术和喷墨印刷技术。比较了采用这两种工艺制造的原型的回波损耗测量结果以及模拟结果。在电波暗室中，将基于ENrG薄型电子层的最佳原型与基于Arlon 25N的原型在辐射特性方面进行了比较，并得出了结论。
