   "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." -
