A New Dielectric Resonator Antenna Operating with Magneto-Dielectric Materials Based in Y3FE5-2xBIxBx Garnets

Abstract

The main objective of this work was to study the dielectric properties of the GdIGxYIG1-x ferrite composite material at radio frequency (RF) and microwave frequency bands were studied. These measurements were carried out in different sample geometries thick films and cylindrical ceramic bulk ferrite resonator. In the RF range, we observed that the material is rather stable because of its short changes as a function of temperature and frequency range. The temperature capacitance coefficient samples presented short positive values at the RF range In the study of the dielectric properties of the composites antenna geometry, with the same ferrite composite, a bulk cylindrical geometry was also investigated.
