Abstract: This paper presents the current development trends of electric field intensity calibration technologies domestically and internationally. The research status of TEM cells, GTEM cells, coaxial cone TEM cells, monocone TEM cells, microwave anechoic chambers, and electromagnetic reverberation chambers in universities, research institutes, and metrology institutions worldwide is emphasized. The design structure and performance parameters of various devices are introduced. A comparison is made between the characteristics, applications, and suitable environments of the various electric field intensity calibration equipment mentioned in this paper. Lastly, based on the research progress of electric field intensity calibration technology, the development trend of on-site electric field intensity calibration to meet the rapid calibration requirements of field strength sensors under production line field conditions is proposed.
