Abstract :
This paper presents a novel compact and tunable metamaterials antenna. A compact left handed transmission line resonator antenna implemented on ferrite substrate is designed to have tunable operation frequency from 5.25 GHz to 5.8 GHz. The antenna length is only 5.8 mm length which is only 45% compared to a conventional antenna operates at the same frequency. The operation frequency can be tuned by varying the applied DC magnetic bias applied to the ferrite substrate. The antenna structure has small demagnetization factor and hence requires small external DC magnetic bias.
