Frequency tuning of a CRLH CPW antenna on ferrite substrate by magnetic biasing field

The aim of this paper is to present results obtained with magnetically tuned Composite Right / Left Handed CoPlanar Waveguide (CRLH CPW) zeroth-order resonating antenna on ferrite substrate. The CRLH structure consists of series connected CPW interdigital capacitors and parallel connected CPW transmission lines. The experiments demonstrate an antennas frequency tuning of approximately 450 MHz as a result of the variation of a magnetic biasing field between 0 T and 0.26 T.
