Abstract :
This paper has presented a method of size reduction of the CRLH transmission line antenna by using a magneto-dielectric material. The CRLH-TL antenna is composed of two patches and vias, and the magneto-dielectric material is constructed by split ring resonators. The resonant frequency of the antenna is reduced by using the magneto-dielectric material: 7.34% at -1st-order mode and 24.88% at zeroth-order mode. An antenna operated at zeroth-order resonant mode is fabricated and measured. It operates at 1.888 GHz and has a bandwidth of 0.48%, a gain of 0.534 dBi, and an efficiency of 51.7%.
