Dispersion in One-Dimensional Photonic Band Gap Periodic Transmission Lines
Dispersion in periodic microstrip transmission fines was investigated by using S-parameters to calculate the characteristic impedance and the complex propagation constant. Dispersion curves determined from a variety of methods, including simulation with IE3D and measurement with a network analyzer. were compared with an analytic transcendental model providing self-consistent validation of each method. Simulated S-parameters agreed with measurement. including the case of a multi-layered substrate. Very similar dispersion curves were produced using simulated S-parameters, simulated current distributions. analytic calculation and measured S-parameters.
