We present the dielectric properties study of the ceramic [SrBi2Nb2O9] single-phase matrix as well as the [SrBi2Nb2O9 + (%)La2O3] composite. The SrBi2Nb2O9 was doped with lanthanum oxide (La2O3) with 3%, 5%, 10% and 15% proportions. Structural characterization by x-ray diffraction was carried out. The dielectric properties in the radio frequency and microwave ranges are presented. The τf temperature coefficient of the composite samples was obtained experimentally. The Hakki–Coleman method has been used to obtain the microwave properties and HFSS software has been used to obtain the far field properties in order to view possible applications of [SrBi2Nb2O9 + La2O3] as a dielectric resonant antenna.
