Spectral domain analysis of microstrip floating line structures by wavelet expansion method

A spectral domain analysis of microstrip floating line structures by wavelet expansion method is presented. The surface integral equation is converted into a sparse matrix equation by using the Galerkin´s method, with the integral kernel and the unknown current expanded in terms of orthogonal wavelets. Limitations inherited in the traditional orthogonal basis systems are released: The problem-dependent normal modes have been replaced by the problem-independent wavelets, preserving the orthogonality. The trade-off between orthogonality and continuity is well balanced by the orthogonal wavelets. Numerical results are compared with previous published data with good agreement.<>
