Abstract :
We consider the natural modes of a thin kite-shaped dielectric resonator antenna as solutions to the 2-D linear eigenproblem for the Maxwell equations with exact boundary and radiation conditions. This problem is reduced to the set of Muller´s integral equations with smooth and integrable kernels discretised using the adequate quadrature formulas. The eigenvalues are found numerically as the roots of the corresponding determinantal equation. The results of the study of several modes are presented.
