Abstract
The aim of this paper is to describe the results obtained on the radiation pattern scanning of a ferrite supported resonating CPW antenna based on metamaterial transmission lines approach. The scanning effect is obtained as an effect of remarkable properties of the ferrite substrate in the microwave frequencies domain when applying a biasing magnetic field. Data obtained by simulation with a suitable electromagnetic analysis software tool indicate an azimuthal characteristic deviation of ± 9.78° at a working frequency f = 13 GHz for a variable magnetic biasing field between 0 T and 0.16 T. This result is in very good agreement with the experimental data showing a characteristic displacement of +12° ... -10°.
