| Abstract(in English) | The application of a wavelet expansion to the moment method (WMoM) is studied for the analysis of a circular and square loop antenna and a Yagi-Uda circular loop array. The usual expansion and weighting functions are replaced by periodic wavelets defined in the finite interval [0, 1]. The periodic wavelet in [0, 1] is constructed from the cardinal B-spline with the minimum support. Current distributions from the WMoM with the quadratic cardinal B-spline wavelet agree well with the results of the conventional moment method (MoM) and the sparse generalized impedance matrix is obtained which could save computation time. In order to replace the quadratic B-spline wavelet with the Haar wavelet related to the weighting function, the WMoM results exhibit the advantages of shorter computation time and give good agreement with the MoM results. |
