本文对无耗波导上多探头系统的相位能量图作修正,获得一种用固定探头设计成各种直读微波阻抗测量图的几何方法。这种方法避开了在经典代数方法中所遇到的大量的复杂问题,使物理概念更加清晰,致使有可能更进一步改进设计,以达到高精度的要求。本文报导了由这个新观点导出的设计方法的研究趋向。从测试未知阻抗 Z 的两探头系统的分析开始,接着叙述了用新的几何方法对设计的改进,最后给出了两个自动测试未知微波阻抗的实例。其中一例则是在扫频和扫功率下得出的。这些系统仅需要用较便宜的低频信号处理器(模拟的或数字的),以及固定多探头。输出既可以用极标作模拟显示,也可以用精确的数字读出。据作者所知,以往用多探头方法还未曾得出过这样的设计。此外,对过去文献中已发表过的多探头系统也有评论,并与新系统作了比较。
In this paper, the phase energy diagram of the multi-probe system on a lossless waveguide is modified to obtain a geometric method of designing various kinds of direct-reading microwave impedance measurements with a fixed probe. This method avoids the large number of complex problems encountered in classical algebraic methods, making the physical concepts clearer, making it possible to further refine the design to achieve high precision requirements. This article reports on the research trends of design methods derived from this new perspective. Starting with an analysis of two probe systems that test an unknown impedance Z, we next describe the improvements made to the design with a new geometric approach and finally give two examples of unknown microwave impedances that are automatically tested. One example is the sweep and swept power. These systems require only cheaper, low-frequency signal processors (analog or digital) and fixed multi-probes. Output can be used as a standard analog display, you can also use accurate numbers read out. According to the author’s knowledge, such a design has not been obtained before using the multi-probe method. In addition, comments have been made on the multi-probe systems that have been published in the past and compared with the new system.
