Abstract

The method of lines (MOL) is utilized to analyze a class of planar transmission lines with circular or semicircular/elliptical metallic shielding. The authors show how the general MOL principles can be modified so that curved boundary structures can be included. Dispersion diagrams are presented for microstrip and slotline structures with curved metallic shielding as well as for their suspended counterparts in circular and elliptical waveguides. Results show that some of the structures have potential applications at millimeter-wave frequencies because losses in circular waveguide enclosures are generally lower than those in rectangular waveguides
