MULTIPLE MICROSTRIP LINES ON A MULTILAYERED CYLINDRICAL DIELECTRIC SUBSTRATE ON PERFECTLY CONDUCTING WEDGE

The quasi-TEM characteristics of a class of cylindrical microstrip lin es are rigorously determined. The class of microstrip lines considered consists of multiple infinitesimally thin strips on a multilayered di electric substrate on a perfectly conducting wedge. Expressions for th e potential distribution inside and outside the dielectric substrate, charge distribution on the strips, and capacitance matrix of the micro strip lines are derived. The problems of a microstrip line on a cylind rically capped wedge and on a cylindrical dielectric substrate on perf ectly conducting core are also considered as special cases. Sample num erical results based on the derived expressions are given and discusse d.
