Abstract

This paper gives a brief introduction of current methods used to calibrate electric field probes as defined by IEEE Standard 1309 as well as a brief discussion of some inherent problems with the current test methods. The use of a reverberation chamber to evaluate electric field probes is described as an alternative method along with some of the tradeoffs between methods. The use of modal, spatial, and frequency averaging to improve field uniformity levels to that required for accurate antenna efficiency characterizations are also outlined. This paper focuses on the repeatability issues associated with calibrations.
