Abstract : This paper presents the use of a Cylindrical Dielectric Resonator fabricated using Barium Titanate/Vanadium Pentoxide (BaTiO3/V2O5) composite material as antenna. The dielectric constant of the cylindrical pellet is measured to be 49.3. The dielectric resonator has a diameter of 14 mm and height of 1.17 mm. The resonator is energized with a 50 Ω microstrip line etched on FR4 epoxy performing as a Cylindrical Dielectric Resonator Antenna (CDRA). The antenna is found to radiate at a frequency of 9.5 GHz with an impedance bandwidth of 226 MHz. The fabricated CDRA shows good reflection and radiation characteristics with a high gain of 8.22dBi at the resonant frequency. The radiation pattern shows that the proposed antenna has good directivity with reduced back lobes. The proposed antenna can be used for weather monitoring, air traffic control, defense tracking and also in space communications.
