摘要：

In this letter, a novel method for the numerical evaluation of the Green's function for the microstrip slot coupled hemispherical dielectric resonator is presented. The proposed technique is very fast as compared to the conventional method of fourfold integration. In this technique, the homogeneous part of the dielectric resonator antenna (DRA) Green's function is manipulated in such a manner that its source and field terms are expressed in the absolute product form. Then, using method of moments (MoM), the absolute product form is numerically integrated by the product of two double integrations. The input impedance calculation using the proposed technique is almost 48 times faster than conventional technique. The method is very rigorous and general and should find applications in the other hemispherical DRA configurations.
