Novel Dielectric Waveguide Design Studies for mmW Applications

Because of their outstanding transmission behaviour at low costs, dielectric waveguides (DWG) are capable of replacing coaxial transmission lines in many emerging fields of micro-and millimeter waves already. To exploit their full potential, this paper deals with novel DWG cross-section geometry designs as well as material studies assuring improved transmission characteristics compared to conventional DWG designs. Measurement results of the presented designs compared to those of a rectangular DWG are obtained.
