The powder samples were calcined at 700°C and tetragonal phase appeared in the powders before they were sintered at 1250°C for 3h. The undoped samples have a polycrystalline tetragonal structure, but Nd doping into the BaTiO3 caused phase transformation from tetragonal to cubic. The smaller grains (0.35μm) produced with the addition of Nd is associated to the inhibition of grain growth of samples. The powders for each composition were pressed into pellets and tested as dielectric resonator antenna (DRA). It was found that on the actual antenna circuit, each sample showed a resonance frequency at X-band application and a dielectric constant value in the range of 51.25-56.89 and tangent loss was 0.039-0.045, depending on the concentration of the Nd at room temperature.
