The results of experimental measurements of the parameters of antenna-feeder devices using the X-shaped analyzer of the complex reflection coefficient in three modes: at fixed-frequency, vibration meter, vector panorama were presented.
The problem of creating meter of complex reflection coefficient based on the electromagnetic approach using E-plane dividers is studied. Rigorous electromagnetic model of direct and inverse problems of five- and six-port measurements of complex reflection coefficient is derived. Frequency dependencies of model parameters are calculated. Properties of E-plane junctions are investigated.
The problem of creating meter of complex reflection coefficient based on the electromagnetic approach using E-plane dividers is studied. Rigorous electromagnetic model of direct and inverse problems of five-port measurements of complex reflection coefficient is derived. Frequency dependencies of model parameters are calculated. Properties of oblique X- and T-junctions are investigated.
Electromagnetic model for calculation of elements of scattering matrix asymmetrical E-cross divider-converter and method of focusing E-cross converter were created. Measuring of complex reflection from passive loads resulted in error 1%, if the converter was focused.
The five-port automatic network analyzer based upon a new concept has been tested in the 26–37.5 GHz range. Analyzer consists of a symmetrical cross-shaped junction and three directional detectors from the scalar reflectometer. An experimental waveguide cross-shaped junction has been designed and used in a five-port measurement system. Validation of moving loads with |Г|<0.7 resulted in errors...
