The Effects of a Generator’s Active Input Reflection Coefficient in Antenna Gain Measurements

摘要

The problem of determining the reflection coefficient of a generator while it is operating is being tackled in this paper, with emphasis placed on both theory and practical applications. Two particular methods are investigated which are, relatively, simple to analyze and implement. It is shown that they have a close agreement despite the widely different procedures by which they approach the same issue. Additionally, the criticality of the generator active input reflection coefficient in determining the gain of an antenna using the gain substitution technique is shown, highlighting the importance to calculate it.
