how to measure dielectric permittivity
Vector network analysis allows for the characterization of a scattered matrix with reflection [S11] and transmission [S21] factors. These parameters are required to design e.g. a matching circuit for an amplifier. So, S33, which is really the "S11" of port S3, is, due to the clever routing, just S21. And S21 is the one thing we can easily measure! In short: A reflection bridge lets you use S21 to find "S11" on its third port.Page 15: Rfid System S21 Configuration Principles. Parameters controlling the RFID System S21’s configuration are logically organized in groups. For a detailed explanation on the meaning and usage of the parameters, refer to the RFID System S21 Reference Guide.
