Abstract

This paper presents the results in frequency tuning of a CPW antenna based on CRLH (Composite Right/Left-Handed) transmission lines. In order to be tuned, the antenna was made on a ferrite substrate. The tuning is obtained by magnetically biasing this 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 of 12.88 GHz, in very good agreement with the experimental results showing a frequency shift of 450 MHz.
