Discretization in Triangular Microstrip Resonators

"The triangular microstrip resonator with steps in the width is a way to simulate the triangular form by the triangular discrete, its analyze is made using the full wave and concise Transverse Transmission Line (TTL) method in the Fourier Transformed Domain (FTD), in conjunction with the Moment Method. Numerical results of the resonance frequency are presented in graphics in 2D and 3D with the use of the FORTRAN Power Station and MATLAB languages."
