Description
Summary:The application of complex impedance detection shows a trend of multi-direction development. The impedance detection technology at home and abroad has expanded from the traditional fields of physics, electricity and chemistry or other fields. Therefore, under the condition of satisfying precision, the design of equipment needs miniaturization and simplicity more and more. Aiming at this trend, a fixture with coaxial structure is calculated and processed based on theoretical knowledge, and its availability is verified by actual measurement and HFSS simulation. On this basis, the physical phenomena of multiple reflection and electrical delay that cause the measurement error are analyzed, and the analytical compensation algorithm is given.
