✦ Synopsis

This letter describes a modal-expansion analysis of a cylindrical dielectric resonator antenna fed by an embedded coaxial probe. The analysis is facilitated by introducing a cylindrical magnetic wall to enclose the resonator, and then the resulting structure can be treated as a cascaded wa¨eguide discontinuity. Numerical results are presented and compared with experimental data a¨ailable in the literature.
