Abstract

Modeling of ferrite-loaded CBS antennas often makes use of the simplifying assumptions which involve some kind of averaging of the magnetic bias field. Simulations and measurements presented here demonstrate that failure to account for the non-uniform magnitude, as well as direction, of the bias field leads to inaccurate predictions of not only the input impedance, but also of the amplitude radiation patterns.
