"A Conceptual Model for the Reflection Measurements of a Vector Network Analyzer System and its Practical Application" - Abstract - "We present
the gradual building of our conceptual model for the reflection
measurements of a VNA Vector Network Analyzer System. In this way, we
reveal the fundamental idea behind this kind of measurements and prepare
the studier for a deeper comprehension of this subject. Moreover, since
this abstract model is exclusively based on technical specifications
supplied by the manufacturers of system components, it is directly
applicable in practice. To demonstrate this fact, we use a specific VNA
System to compute and draw both the frequency dependent systematic error parameters of it and of the reflection coefficient and input impedance
of a particular antenna we constructed and measured by using it." -
