Design alternatives are suggested for flexible dielectric wave guides with small losses meant for multi-element antenna arrays. A numerical technique is developed to compute eigenvalues and fields for dielectric paths. Numerical investigation results are described allowing to evaluate dispersion features of the dielectric paths with various cross-section forms. An evaluation criterion is offered for the investigation data to extract «false» decisions obtained as a result of a replacement of the complex Green function with its real part.
