On the efficient calculation of the axially probe-fed hemispherical dielectric resonator antenna

Electromagnetic Fields and Currents on Conducting Bodies Excited by Modulated Laser Light - Parts 1 & 2

“…The input conductance of a conducting sphere coated by a dielectric layer, plotted against the thickness of the dielectric layer, is given in Figure 3-27 [53]. Input impedance of a hemispherical dielectric resonator antenna, which is a monopole embedded in a hemispherical dielectric material, is presented in Figure 3-28 [45]- [47]. In Figure 3-29 and 3-30 are given the current and input impedance of a monopole antenna in a finite height dielectric cylinder driven by a coaxial line through an infinite ground plane [38].…”

“…These equations are then solved by the MoM. Dyadic Green's function techniques are well suited for the analysis of probe-excited, hemispherical dielectric resonator antennas [44]- [47]. One of the fundamental configurations of the DR antenna is the axially probe-fed cylindrical DR antenna.…”
