Abstract
The antenna radiation efficiency of a K-band horn was determined using a reference waveguide method with S-parameters in a reverberation chamber. Numerical analysis was performed to validate the applicability of the measurement method and the measured results. In addition, the effect of unstirred waves on the radiation efficiency measurements was evaluated using the complex
$S-\text{parameter}$
method for identifying unstirred waves.
