Inductance extraction of a meander line on a coplanar plane using partial element method

This paper proposes an inductance extraction method for a compact meander line structure. The Green House algorithm is introduced to solve the complicated inductive coupling effects and make it possible to calculate a meander line with any shape. Three different cases with a meander line or a straight line as a return path are discussed. Self and mutual inductances are demonstrated based on partial element theory, and then the loop inductance for the three structures are derived. The effect of the gap between adjacent signal and return lines on the mutual inductance is also addressed.
