characteristic impedance of suspended stripline

Hello everyone,

This was haunting me quite some time. I really want to know how to calculate the characteristic impedance of a suspended stripline. I know there are some tools that can calculate all the parameters like Zo, physical length, width, etc but there's none for suspended stripline.
Let say i have this values:

frequency 2GHz
Dielectric constant 2.2
width 14mm
thickness 0.254mm
height 10mm

Thanks

Do you have access to software such as HFSS? I know in HFSS in particular, you can place a waveport over your TL and it will solve for the modal impedance(s). There are probably several other numerical solvers to achieve the same results.
