The analysis of cavity backed, slot excited dielectric resonator antennas (DRA) is accelerated with the use of a macromodel within the framework of the IE-MoM formulation. The macromodel can be regarded as a projection of complete information about the DRA onto the slot in a wide frequency range, and thus it provides huge reduction in the total number of unknowns. Consequently, this enables a considerable decrease in computation time and makes it possible to curry out fast optimization of a feeding network structure enclosed in a cavity without the need for handling large systems of linear equations associated with the DRA.
