The algorithm is applied to a microstrip line-fed patch antenna (MPA) with anisotropic substrate. Numerical results demonstrate that the anisotropy in the substrate effects the resonant frequencies of the MPA. The speeding up technique reduces the required computation time of the Lossless-ANI algorithm.eninfo:eu-repo/semantics/closedAccessFDTDLossless Anisotropic MediumConference Object
