Abstract
We derive the systematic uncertainty of the efficiency for the reflection method. And we evaluate the uncertainty of the efficiency for 40 mm monopole antenna using measured 64 reflection coefficients in the cavity and find that the uncertainty is not always dominated by the measurement in the cavity. In future, we will evaluate the uncertainty for various combinations of the sliding shorts.
