Abstract :
A quasi-static analysis is carried out to examine the capacitive coupling between two nonintersecting orthogonal microstrip lines above a ground plane and in a dielectric substrate. The charge density along the width of each strip is described using a prescribed charge distribution. A pair of coupled integral equations is derived and solved by the method of moments to obtain the excess charge densities. The lumped excess capacitances are computed and compared to those obtained using wire lines with radii equal to the equivalent radii of the strips
