Abstract :
When computing the permeability tensor of the ferrite material, it is often assumed that the internal magnetic field is uniform. In this paper we compare simulations and measurements of the input impedance of a ferrite-loaded CBS antenna based on the non-uniform field distribution with those based on the uniform field distribution.
