Microstrip antenna analysis using the method of fundamental solutions. (English) Zbl 1158.78007

The method of fundamental solutions is a simple tool which is based on the linear combination of known fundamental solutions of the Helmholtz equation. This method is proposed in the present paper for the analysis of microstrip patch antennas. Resonance frequency results have been obtained for rectangular, circular and triangular patches. In the implementation and formulation developed in this work, the method of fundamental solutions assumes that electromagnetic fields and the excitation current are constant along the substrate thickness. This is the main reason for which this method can be used only for thin substrates. Numerical simulations conclude the present paper.
