Inductance and characteristic impedance of a strip-transmission line

Abstract

A general method is deve loped for de termining th e inductance and characteristic impedance of uniform transmi ss ion lines. A non·uniform current distribution is allowed in the trans verse plane. Th e system is represented by a matrix equation whi c h can be programmed for computer solution. The co rrect inductance and impe dan ce are obtained as th e res ult of a simple limiting process. The method is applied to one parti c ular geometry, a four-tape s triplin e system . Re s ults are given for the indu ctan ce, resistance, and c urrent di stribution as functions of frequ e ncy and resistivity for a particular geometry_ A me th od for ex te nding th e res ults to st rip lin es with proporti onal dimensions is developed. An accuracy of one part in 10 5 was found to be feasib le for th e determ in ation of th e inductance per unit le ngth.Key Word s : C ha racte ri sti c impe d ance, indu cta nce, and slrip-tran s mi ss ion lin es.

“…The electron beam travels between the two conductors in the region where fields, as shown by Brooke [6], are almost uniform if the center conductor is made sufficiently wide.…”
