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 sources and provides insight into how a structure resonates at the calculated frequencies. This information can be used to excite the structure with the desired modes only.
