This work is supposed to contribute to the development of researches in the area of Patch Antenna. The general purpose involves a Microstrip antenna on Photonic Band Gap structure. The use of this structure implies in the reduction of the troublesome surface waves that plague the performance of these antennas and complicate its theoretical modeling. The(More)
A computational code has been developed for analyzing 3-D radiation problems in curved geometries. To accomplish this, a suitable formulation is developed considering Maxwell equations in a general coordinate system and numerically solved by the use of a parallel curvilinear finite-difference time-domain (FDTD) method. In order to validate the computational(More)
