Contents I. Introduction
Transmission of high frequency signals plays an increasingly important role for various applications such as radar, mmW imaging or high speed communication. As an efficient transmission behaviour is often accompanied by high production costs (e.g. high precision RF coaxial cables and connectors) or inflexibility and high weight (e.g. metallic waveguides), dielectric waveguides respresent a convenient technology for future transmission systems, providing considerable flexibility, small weight and low attenuation losses at low manufacturing costs. But in order to integrate DWGs into final industry products, further research on topics like shielding concepts (e.g. [1]), connectivity (e.g. [2]), geometry or material selection is still necessary. In order to compare dielectric waveguide characteristics with datasheets of established transmission line concepts like e.g. coaxial cables or metallic waveguides, this paper provides typical transmission line characterization measurement results for return loss, insertion loss, bending angle, bending radius, reproducibility and interference resistance with regard to magnitude and phase stability.
