Abstract :
This paper presents the results in frequency tuning of a ferrite supported resonating CPW antenna based on CRLH (composite right/left-handed) transmission lines. The tuning is obtained by magnetically polarizing the ferrite substrate with a magnetic biasing field variable between 0 T and 0.26 T. Data obtained by simulation with a suitable microwave software indicate a frequency shift of 530 MHz at a working frequency 12.88 GHz, in very good agreement with the experimental results showing a frequency shift of 450 MHz.
