Electromagnetic axisymmetric analysis of monopole antenna over a perfectly electric ground plane by a Meshless Local Petrov-Galerkin method

摘要

This work describes a meshless method to obtain the electromagnetic characteristics of a monopole placed over a perfectly electric ground plane. The Meshless Local Petrov-Galerkin is used with shape functions generated by Moving Least Squares. Boundary conditions are imposed by a collocation method that does not require any numerical integration. The proposed axisymmetric analysis has a simple implementation and reduced computational effort. The results are in agreement with theoretical data and simulations found in the literature.
