Abstract :
Passive microstrip elements are analyzed by the full-wave, space domain moment method at microwave frequencies. Redundant calculations in the moment matrix are eliminated by using various symmetries manifested by the Green´s functions. The Green´s functions are, in general, Sommerfeld-type integrals, which are computationally intensive. Recently developed closed-form analytical approximations of the integrals are used to increase the efficiency of the algorithm. Spatial interpolation of the moment matrix and the Green´s functions is performed. Sample computed results are presented for the scattering parameters of meander lines and multiturn spiral inductors.<>
