Abstract
A rigorous analysis of the slot-coupled hemispherical dielectric resonator top-loaded by a conducting cap is presented. The resonant frequency of the antenna can be tuned by changing the size of the loading cap. Measurements were carried out to verify the calculations, and reasonable agreement between theory and experiment is obtained.
