Abstract

One of the non-resonant techniques is the free-space measurement technique, which is popular due to its many advantages compared to the other techniques. It allows the transmission and reflection measurements without any physical contact with the sample. This paper discusses the free-space material measurement system in Ku-band which uses the NRW algorithm and Keysight (Formerly Agilent) 85071E software in determining the dielectric properties of materials. The permittivity and permeability of Teflon, FR4, PVC, ABS, Acrylic, polypropylene, polycarbonate, and epoxy were determined using free space measurement setup. For the first, a free-space measurement for Ku-Band is setup. It consists of a vector network analyzer, two horn antennas, sample holder, and Keysight 85071E software. The different role of transmission and reflection measurements on the achievable results is analyzed about experimental uncertainties and different noise scenarios. Results from the two strategies are analyzed and compared. Good agreement between simulation, measurement, and literature was obtained.

库班微波材料自由空间测量系统

其中一种非谐振测量技术是自由空间测量技术，由于其与其他技术相比具有许多优点而受到欢迎。它允许传输和反射测量没有任何物理接触的样品。本文讨论了ku波段自由空间材料测量系统，该系统采用NRW算法和Keysight(原Agilent) 85071E软件来测定材料的介电性能。采用自由空间测量装置测定了铁氟龙、FR4、PVC、ABS、丙烯酸、聚丙烯、聚碳酸酯和环氧树脂的介电常数和磁导率。首先，建立了ku波段的自由空间测量。它由一个矢量网络分析仪，两个喇叭天线，样品支架和Keysight 85071E软件组成。在实验不确定度和不同噪声情况下，分析了透射和反射测量对可达结果的不同影响。对两种策略的结果进行了分析和比较。仿真、测量和文献结果吻合良好。
