Coplanar Transmission Line Formulas

[Yooli]

Hi guys,

I need the formulas for Capacitance, Inductance and (Im) Impedance
of a coplanar Transmission Line (or coplanar waveguide).

Also, design considerations of a coplanar microwave resonator
would be of great use.

Any Papers or articles known ?

Thank you very much in advance (this community is really great!),

A good book with closed formulas about coplanar and microstrip is: "Microstrip lines and Slotlines" Gupta et al.

it is not simple as a formula can represent. Use HFSS to simulate and U will be suprised by the difference.

Cheers

Try to use TX*line from MWO2002 (free) or similar program in S*e*r*e*n*a*d*e 8.5. In MWO-help You may find some links to papers.

I have in my hands a new book full of very useful info for coplanan design:
Coplanar waveguide circuits, components and systems, by Rainee N. Simons, Wiley Series in Microwave-ISBN 0-471-16121-7.
It is a good book, including usefull formulas, transitions and other usefull topologies.
You can use HFSS or Coplan library for most of your designs.
