This work deals with a full procedure for the evaluation of the power radiated by an antenna from a nonredundant number of near-field measurements collected by means of the innovative planar wide-mesh scanning. It uses a sampling interpolation formula for computing the radiated power from the radiation intensity samples on the far-field sphere. Such samples are determined via a probe compensated near-field - far-field transformation. An optimal sampling interpolation formula is also used for their evaluation. It can be applied for the antenna directivity evaluation whenever the power radiated by the antenna in the backward half-space is negligible. Numerical simulations assess the effectiveness of the proposed procedure.

Abstract

This work deals with a full procedure for the evaluation of the power radiated by an antenna from a nonredundant number of near-field measurements collected by means of the innovative planar wide-mesh scanning. It uses a sampling interpolation formula for computing the radiated power from the radiation intensity samples on the far-field sphere. Such samples are determined via a probe compensated near-field - far-field transformation. An optimal sampling interpolation formula is also used for their evaluation. It can be applied for the antenna directivity evaluation whenever the power radiated by the antenna in the backward half-space is negligible. Numerical simulations assess the effectiveness of the proposed procedure.
