Coaxial cable is a type of cable for high bandwidth data transmission use that typically consists of a single copper wire that is surrounded by a layer of insulation and then by a grounded shield of braided wire or an extruded metal tube. The whole thing is usually wrapped in another layer of insulation and, finally, in an outer protective layer. This paper proposes new designs to eliminate attenuations present in the transmission line by means of perfect matching of the ports through two models coaxial cable and rectangular waveguide. This paper also depicts the various conditions for propagation of waves through the structures.
