An Ultra-Broadband Probe for RF Radiation Measurements

Recent awareness to the problem of harmful exposure to microwave radiation has stimulated the search for convenient and accurate methods of measuring the intensity of this radiation. Although much has been accomplished so far, there remains much to be done. In particular, the aspect of broadbanding a given probe design is crucial if exposure to multifrequency radiation fields is to be anticipated. This paper deals with this question and describes the design and performance of a probe built in accordance with the principles developed in the theoretical portion of the paper.
