Correction to “Determination of the Generalized Scattering Matrix of an Antenna From Characteristic Modes” [Sep 13 4848-4852]

On page 4850 of the above-named work [ibid., vol. 61, no. 9, pp. 4848???4852, Sep. 2013], the sentence that starts with "We assume that the eigenvalues of the higher-order modes are very large compared with the eigenvalue of the lowest-order mode so that the currents on the antenna and the input admittance are dominated by the lowest-order mode only ..." should be replaced by the corrected sentence given herein.
