Antenna simulations with surface integral equations of the second kind and high order basis functions

In this talk, magnetic field integral equation (MFIE) and electric field integral equation (EFIE) are applied in the analysis of metallic perfectly conducting antennas. We compare an EFIE-RWG solution with the MFIE and CFIE high-order solutions and show that, the more singular solution is, the higher the order of the basis functions and the finer the discretization should be, in order to obtain the same solution accuracy with MFIE and CFIE as with EFIE and RWG functions.
