本文介绍了一种在微波硬件和计算机软件两方面都改进和优化了的六端口反射计。所报导的优化六端口网络是使三个原点对称地分布在复反射系数Γ平面上。这种六端口网络是由正交定向耦合器和同相功率分配器组成。在软件方面,所采用的自校技术和准确度提高技术,使不精确的功率测量得以改善。除理论探讨外,文中还给出了实验结果,并与标准参考数据作了比较。 This article presents a six-port reflectometer that has been refined and optimized in both microwave hardware and computer software. The reported optimized six-port network is such that the three origins are symmetrically distributed over the complex reflection coefficient Γ plane. This six-port network is composed of quadrature directional couplers and in-phase power dividers. On the software side, the self-calibration techniques and accuracy-enhancing techniques used improve inaccurate power measurements. In addition to the theoretical discussion, the experimental results are given and compared with the standard reference data.
