In this study the electroceramics based on Ca(Nb2/3Li1/3)xTi1−xO3-δ, for x between 0 and 1, were prepared by the traditional solid state method. DRA in cylindrical shape with probe-feed cylindrical were investigated. The dielectric permittivity and loss of the CNLTOX alloy were analyzed in the region of 2 to 4.5 GHz. The frequency response around the first mode (HEM11δ) was determined by the HFSS (High Frequency Structure Simulator) program and these results were compared to the experimental setup. In this procedure, significant parameters of the DR were obtained. The experimental and theoretical characteristics of the resonator (return loss, bandwidth and input impedance) are in good agreement. These measurements confirm the possible use of such material as small dielectric resonators.
