(a) Rectangular metal waveguide to high dielectric constant ribbon waveguide transition [17]. (b) Longitudinal cross-sectional geometry of a polymer-coated high dielectric constant ribbon. The thickness and the width of the high dielectric constant ribbon are 0.0635 and 0.635, respectively. The thickness of the polymer coating is approx. 0.25 and the width is approx. 0.635. The dielectric constant of the ribbon is 10 while that of the polymer is 2.04 [17].
