Using a dyadic Green's function formulation, a rigorous analysis of the two-disk stacked microstrip antenna is performed. Using the vector Hankel transform, the mixed boundary value problem is reduced to a set of coupled vector integral equations. Employing Galerkin's method in the spectral domain, the complex resonant frequencies are calculated as a function of the layered parameters and the ratio of the radii of the two disks. For each mode, the stacked microstrip antenna has dual resonant frequencies associated with the constitutive resonant cavities of the structure. > |
