IV. CONCLUSION

In this letter, we present a spectral domain analysis of arbitrarily shaped microstrip discontinuities. A powerful technique is obtained by combining an electric field integral equation with a method of moments, using a division of the circuit into triangular cells and overlapping basis functions. Numerically matched loads using triangular ghost basis functions are used in order to improve the numerical procedure for extracting the scattering parameters of arbitrarily shaped microstrip discontinuities. In order to illustrate the efficiency of this technique, characteristics of compensated microstrip right-angle bends and a 45Њ microstrip bend are investigated. The results are in agreement with published data.
