A microstrip patch antenna is analyzed to demonstrate the efficiency and accuracy of the hybrid technique for the evaluation of the Method of Moments (MoM) reaction integrals containing closed form Green's functions. The proposed hybrid method can reduce the matrix fill-time significantly, without sacrificing the accuracy, with an appropriate choice for ρls. The proper choice of ρls depends upon the Green's function, as well as on the cell size used for discretization, and that the choice of ρmax should be carried out in accordance with the magnitude of the Green's function at ρmax.
