Abstract

In this work, the influence of the addition of Bi2O3 on the dielectric properties in the microwave range of BiCu3Ti3FeO12 (BCTFO) ceramic matrix and its potential application as a dielectric resonator antenna are analysed. X-ray diffraction shows that a reaction between BCTFO and Bi2O3 occurs that results in the formation of new crystalline phases. The morphology of the samples is studied by field-emission scanning electron microscopy and demonstrates a dependence of the grain size on the Bi2O3 content. From the Mössbauer spectroscopic analysis, it is found that the Fe3+ ions replace the Ti4+ in the crystalline structure. The addition of Bi2O3 also reduces the dielectric permittivity (ϵr), dielectric loss (tan δ) and the coefficient of the resonance frequency (τf) values. Finally, numerical simulations are carried out in order to obtain the antenna parameters and they demonstrate that BCTFO could be a potential candidate for devices operating in the S-band.
