Abstract

In this work, a novel method is presented, with which the safe space around aperture antennas can be assessed. The basis of this new approach is the approximate similarity of the contours between uniformly and non-uniformly illuminated apertures. The isoparametric contours that result from numerical calculations have to be replaced by envelope contours that fully enclose them, in order to avoid radio frequency hazards. These envelopes were approximated with analytical formulas. Various examples of different apertures are presented, which demonstrate the mode of application and the validity of our method.
