“…As expected, the chamber loss increases over frequency. These results show, compared to other reverberation chambers operating at these frequencies, that the chamber used in this work has a significantly lower chamber loss [5], [8], [11]. With the settings used in these setups, the noise floor of the VNA was approximately at -100 dBm.…”

“…Research on devices in 6G bands is well on its way, which creates a need to construct new characterization methods for active array antennas operating in bands towards 100 GHz [3]. Historically, RCs have mainly been used for measurements at sub-6 GHz frequencies, but recent trends show mm-wave chambers that operate up to 60 GHz [1], [4]- [8]. However, to the author's best knowledge, no antenna-efficiency results have been published above 47 GHz [1].…”

“…These are data from the single-paddle, simultaneous measurement setup efficient measurements of receiver sensitivity with the flexibility of a large test volume at much lower loading and less stringent spatial averaging. At millimeter-wave frequencies, we have achieved CBWs up to 60 MHz [27,28], but optimisation of the spatial stirring becomes paramount. Given this robustness and flexibility in device size, shape, and placement of the reverberation chamber, it serves as a cost-efficient test method for the wide array of IoT and NB-IoT form factors in development.…”

The next generation of wireless device utilises higher frequencies and a large array of form factors. With miniaturisation of devices and the growth of internet‐of‐things applications having no connectors for testing, the use of conducted tests is no longer an option and verification of this equipment requires over‐the‐air measurements. Additionally, some important metrics such as receiver sensitivity requires an actual communication link. Reverberation chambers loaded with lossy absorbers provide an efficient environment to measure such averaged quantities with flexibility in a test volume as well as device size, shape, and placement. Here, the authors present an overview of OTA measurements in reverberation chambers compared to anechoic measurements. The authors show the consistency and flexibility of reverberation chambers through measurements of a wireless device in three different reverberation chamber setups and compare to an anechoic chamber measurement. By using a proper chamber setup, and by showing a coherence bandwidth (CBW) as a universal metric for comparing chamber loading between setups, excellent chamber‐to‐chamber consistency is shown, without precise placement of the device in each chamber. The authors show empirical evidence for the choice of threshold in determining the CBW.
