Abstract :
The characteristic impedance of asymmetrical coplanar waveguide (ACPW) was calculated using multi-resolution time domain (MRTD) method which based on Daubechies compactly supported scaling functions. The good agreement between this paper and the conventional FDTD method was obtained. Efficiency of MRTD method was compared with FDTD method. Time and frequency domain results have been presented and explained. The curves of characteristic impedance varying with frequency were drawn from 1GHz to 60GHz. The effect of side strip width on characteristic impedance was analyzed.
