本文系统地研究了电工纺织品的高频电性能。首先，用波导腔方法完成导电线的表征。包括导电线密度的影响和几种不同类型的导电线的比较。其次，通过微带谐振器方法比较了针织图案和编织图案的有效电导率。详细介绍了各种编织图案对导电损耗和介电损耗的影响。最后，通过电纺织贴片天线的制造和测量显示了电纺织材料的高频特性的相关性。全织物贴片天线的效率高达78%，由于使用低损耗的电纺织品在本文中的特点。
A systematic study of the high frequency electrical properties of electro-textiles is presented in this paper. First, conductive thread characterization is completed with a wave-guide cavity method. The effect of conductive thread density and comparison of several different types of conductive threads are included. Second, comparisons of knitted patterns and weave patterns are made in terms of effective electrical conductivity through a microstrip resonator method. The effect of various weave patterns on conductive and dielectric loss is detailed. Finally, the relevance of the high frequency characterization of the electro-textile materials is shown through electro-textile patch antenna fabrication and measurements. The efficiency of the fully fabric patch antenna is as high as 78% due to the use of low loss electrotextiles characterized in this paper.
