A dielectric resonator excited by a coaxial probe and designed for an omni‐directional pattern is considered. Combining two dielectric resonators of different dielectric material with each other enhances bandwidth. The effect of antenna parameters such as dielectric constant and probe length are investigated. The analysis is performed numerically, using the method of moments and verified by the FDTD method. The agreement between the two methods is excellent. A 45% bandwidth is achieved with this structure. © 2002 Wiley Periodicals, Inc.
