Abstract :
The paper describes a method to analyze arbitrary metallization thickness on a coupled microstrip line for RF MEMS passive device design. Using a conformal mapping technique, closed-form expression quasi-static parameters for the metallization thickness of coupled microstrip lines are determined. They are found to be accurate compared with simulation tools. By using this method, the even-odd mode impedance of coupled microstrip lines for arbitrary metallization thickness can be obtained.
