It has previously been shown that radiation efficiency and input reflection coefficient Slits of small antennas in free space can be obtained from measurements in reverberation chamber. The S-11(fs) is obtained by so-called complex stirring of the S-11 measured when the antenna is in the chamber. In the present paper it is shown that the accuracy of S-11(fs) can be very good even for larger directive antennas at high frequency provided additional complex frequency stirring is applied. The corresponding deterioration loss in frequency resolution is small at high frequency, in the relative sense. The presented S-11(fs) results match results measured in anechoic chamber down to -40 dB.
