摘要: In this work, we fabricated ceramic composites based on the composite matrix Sr2CoNbO6 (SCNO)-TiO2. The SCNO was synthesized by solid-state reaction, and x-ray diffraction used for structural characterization of synthesis. We measured dielectric properties in microwave range using Hakki–Coleman method, as well thermal stability these frequency range. inserted TiO2 an order to improve SCNO. cylindrical resonators were concentrations 5 wt.%, 10 20 40 60 80 wt.%. insertion improved stability, loss, permittivity SCNO-based ceramic. These evaluated resonator antenna, performance materials presented a reflection coefficient below −10 dB, gain above 2.5 dBi, efficiency 60%.
