Rectangular and Triangular Multilayer Microstrip Resonators

Rectangular and triangular discretized multilayer microstrip resonators, analyzed using the full wave TTL - Transverse Transmission Line method in the spectral domain, jointly with the moment method is presented. The Homogenization theory is used to calculate the equivalent permittivity for the s and p polarizations of the structure composed of PBG (Photonic Band Gap) material. New numerical results of the resonance frequency for the rectangular and triangular multilayer, on isotropic and anisotropic PBG material substrate resonators are presented.
