HIGH FREQUENCY ELECTROMAGNETIC FIELD SENSORS AND SMALL, INTEGRATED ANTENNAS: CHALLENGES FOR THE FUTURE

Guy A. E. Vandenbosch

Abstract

In this educational overview paper it is shown that the traditional distinction between on the one hand ElectroMagnetic (EM) field sensors and on the other hand “antennas” is slowly disappearing at higher frequencies. First a definition of both components is given. Second, the fundamental difference between both components is discussed. Third, it is shown that at very high frequencies, both definitions actually “merge”, resulting in a single component. The fact that in practise, higher and higher frequencies are indeed used in many applications should invoke an intense cooperation between the two research communities, the one involved in the analysis and design of EM sensors, and the one involved in the analysis and design of antennas. Also, the modeling tools used in both communities are based on the same fundamental principles. Cooperation there is also of mutual interest. The current trends and challenges for the future are discussed briefly. During the presentation, they will be addressed extensively.
