Abstract

The authors report a study on microwave properties of a ferrimagnetic ceramic composite (Gd3Fe5O12)GdIG X-(Y3Fe5O12)YIG1-X. The magnetic and dielectric measurements at microwave frequency were made through the Hakki-Coleman's procedure and through the excitation of a cylindrical ferrite resonator antenna (FRA). The hysteresis loops of the GdIG XYIG1-X ferrimagnetic composite were obtained. The numerical simulation study was performed using Ansoft's High Frequency Structure Simulator (HFSS™) software. The agreement between the experimental data and the simulated results is very good. These results demonstrated that, by varying the material composition of the resonator, ferrimagnetic composite GdIGXYIG1-X could operate as a magneto-dielectric antenna with bandwidth in the range of 7.5-11 and in the frequency range of 4.4-5.3GHz. Additionally, all FRAs presented a low negative value of tf, which indicates suitability for microwave applications such as mobile communication systems or satellite broadcast systems. © The Institution of Engineering and Technology 2009.
