Abstract :
Investigations on compact dielectric resonator antennas are presented. Low-loss, high dielectric constant zirconium tin titanate (ZST) material was prepared by using solid state reaction method. The ZST resonators exhibit 36 dielectric relative permittivity, dielectric loss tangent 5×10-4 and resonant frequency temperature coefficient between -4 to +4 ppm/°C. The developed resonators are very attractive for probe-fed resonator antenna for 2.66 GHz.
