In this paper, the microwave network analysis of the dispersion characteristics for various dielectric waveguides is presented, and the effective dielectric constants of the waveguides are given. Compared with the results obtained by experiments and the mode matching as well as the finite element methods, it has been proved that the present method is applicable for different dielectric structures with higher accuracy, especially in the region far away from the cut off frequency. Therefore the method is particularly satisfactory for meeting the practical requirements of engineering design, and is a simple and useful estimating method for engineering application.
