Abstract: A wideband cylindrical dielectric resonator antenna with high dielectric constant is proposed, analyzed and designed. The ceramics cylindrical dielectric resonator antenna with an air gap excited by an H-shaped slot is adopted to overcome the narrow bandwidth under the condition of high dielectric constant. An impedance bandwidth of 12.6% has been achieved with a smaller size of the dielectric resonator and better radiation performance.

Key words: ceramics, H-shaped slot
