Application of MRTD on Novel Ultra-Wideband Bandpass Filter

Abstract

A novel compact asymmetrical coplanar waveguide (ACPW)-fed ultra-wideband (UWB) bandpass filter is proposed in this paper, and the application of multriresolution time-domain (MRTD) formulation technique to the modeling of UWB ACPW filter is facilitated. The numerical and measured results demonstrate the advantages of MRTD over conventional FDTD method with respect to memory and mesh requirements and execution time, the correctness and effectiveness of MRTD method are verified by the results.
