Practical transmission line analysis (striplines)

Abstract

It is demonstrated that a simple formula can produce essentially the same results as a more costly finite element method analysis for dual stripline characteristic impedance. This formula can analyze the effects of undercut in both dual stripline (offset stripline) and in conventional stripline. Because the simple, closed-form solution uses little central processor unit time, it is ideal for embedding into a computer-aided design program that designs transmission lines.<>
