This paper aims to present the characteristics of an dielectric resonator antenna (DRA) made from alumina ceramic matrix (Al2O3) with the addition of titanium oxide (TiO2), the method used to improve the dielectric properties of the ceramic matrix favoring its use in microwave and RF circuits. After analyzing the results, it was confirmed the material as a good alternative for application in telecommunications as ARD, with gains around 3,76 dBi and 99,07% efficiency
