On Mutual Coupling and Coupling Paths Between Antennas Using the Reaction Theorem

The reaction theorem is applied to antenna coupling problems. It is shown that the reaction theorem can be used to calculate the mutual impedance between antennas, when the electromagnetic fields are known on a plane that separates the antennas in two disjoint regions. We also show that coupling pat...

Zusammenfassung:The reaction theorem is applied to antenna coupling problems. It is shown that the reaction theorem can be used to calculate the mutual impedance between antennas, when the electromagnetic fields are known on a plane that separates the antennas in two disjoint regions. We also show that coupling paths between the antennas can be visualized by using intermediate results from the reaction theorem. The coupling paths are visualized based on the fields generated by each of the two antennas, and only take into account the energy that is actually transferred between the antennas. The visualization of coupling paths is useful for understanding how the coupling between the antennas is distributed in space.
