In this paper, we have implemented a numerical tool using finite element method (FEM) for designing an antenna for MRI (Magnetic Resonance Imaging) probe operating at high field. The birdcage antenna type is a transverse electromagnetic (TEM) coupled lines resonator, and the developed model in the absence of a biological load is based on the propagation equations of voltages and currents on the coupled...
Using the finite element method (FEM) and method of moments (MoM) in two dimensions, the electromagnetic (EM) analysis and design of a n-element coupled-microstrip-line quasi-TEM resonator are presented. The analysis allows the determination of the primary inductive and capacitive matrices ([L], [C]) and simulates the frequency response of S11 at the RF port of the designed n-element inhomogeneous...
