MIMO Elliptical Ring Antenna (Characteristic Modes)
Calculate the current distribution and far fields for a MIMO elliptical ring antenna. Use characteristic mode analysis to calculate the results for different modes.
The analysis is independent of any sources and provide insight into how a structure resonates at the calculated frequencies. This information enables excitation of the structure so that only the desired modes are used.
