Simplified approach to probe-corrected spherical near-field scanning
Abstract
A multipole representation for the response of an arbitrary receiving antenna is derived that allows the formulation of probe-corrected, spherical near-field scanning simply in terms of conventional vector spherical harmonics. Both the representation and formulation are free of rotational and translational addition theorems. A sampling theorem derived for Legendre functions is used to evaluate the resulting orthogonality integrals by direct summation in a computer time proportional to (ka)-cubed.
