ZUNIGA-JUAREZ, José Eleazar; REYNOSO-HERNANDEZ, J. Apolinar; MAYA-SANCHEZ, María del Carmen  e  MURPHY-ARTEAGA, Roberto S.. A New Analytical Method to Calculate the Characteristic Impedance Z_c of Uniform Transmission Lines. Comp. y Sist. [online]. 2012, vol.16, n.3, pp.277-285. ISSN 2007-9737.

A new analytical method to calcúlate the characteristic impedance of transmission lines embedded in identical, symmetrical and reciprocal connectors is herein presented. To calcalate the characteristic impedance of transmission lines, the proposed method uses S-parameter measurements performed on two uniform transmission lines having the same characteristic impedance and propagation constant but different lengths. The method was successfully applied to characterize microstrip lines printed on an FR4 substrate in the 0.45-4GHz frequency range.

Palavras-chave : Characteristic impedance; propagation constant; microstrip line; symmetrical-reciprocal connectors.
