coupled suspended stripline between ground plane in odd mode

[Mark Burford]

Am making a model of a couple transmission line as in subject, I am
struggling to find a geometry based formula for the capacitance to ground
and mutual capacitances.

I was using the parallel plate capacitance formula and am currently looking
for the fringing capacitance to add on to it in true engineering
approximation style.

Can anyone help please? I need a formula in terms of the dimensions of each
stripline.

Hi Mark,

Get a hold of an old Motorola MECL databook. It's all in there.
