S21 measurement data inside a mode stirred reverberation chamber

Reverberation chamber (RC) is a metal cavity which is often used for EMC measurements. During the last couple of decades, RCs have proved itself to be a useful tool for Over-the-air (OTA) measurements such as antenna efficiency, diversity gain, etc. A well mode stirred RC produces Rayleigh fading environment which is considered as a common test environment for testing wireless devices such as mobile phones in GSM, WCDMA, UMTS and LTE frequency ranges. Studies have shown OTA characterization of wireless devices inside RC in terms of OTA throughput, TIS (Total Isotropic Sensitivity) and TRP (Total Radiated Power) have very good agreement with OTA measurements inside Anechoic chambers.The given dataset is a callibration data, i.e. S-parameters measured using Vector Network Analyzer (VNA). More specifically, the dataset consists of only S21 measured between two antennas inside RC. The RC has several mode stirrers and there is no direct line-of-sight between the two antennas. The measurement is done using stepped stirring configuration meaning that the stirrers were static when VNA was sweeping thru the frequency range. The measurements were divded into 3 parts due to the limited frequency of operation of callibration antennas, i.e. 0.5 - 2.0 GHz, 2.0 - 6.0 GHz and 6.0 - 50.0 GHz. The data set may be extended up to 67 GHz in the future. We have measured 600 samples per frequency point and the measurement resolution is 1 MHz.
