General Analytic Correction for Probe-Position Errors in Spherical Near-Field Measurements
A general theoretical procedure is presented to remove known probe-position errors in spherical near-field data to obtain highly accurate far fields. We represent the measured data as a Taylor series in terms of the displacement errors and the ideal spectrum of the antenna. This representation is then assumed to be an actual near field on a regularly spaced error-free spherical grid. The ideal ...
متن کاملExperimental Testing on an Effective Technique to Reconstruct the Far- Field Pattern of a Long Antenna from Near-Field Measurements Acquired via Spherical Spiral Scan
In this paper, the experimental validation of a fast and accurate near-field – far-field (NF–FF) transformation with spherical spiral scanning for elongated antennas is provided. Such a transformation relies on a nonredundant sampling representation of the voltage measured by the probe, obtained by using the unified theory of spiral scans for nonspherical antennas and adopting a cylinder ended ...
متن کاملA Study of Electromagnetic Radiation from Monopole Antennas on Spherical-Lossy Earth Using the Finite-Difference Time-Domain Method
Radiation from monopole antennas on spherical-lossy earth is analyzed by the finitedifference time-domain (FDTD) method in spherical coordinates. A novel generalized perfectly matched layer (PML) has been developed for the truncation of the lossy soil. For having an accurate modeling with less memory requirements, an efficient "non-uniform" mesh generation scheme is used. Also in each time step...
متن کاملTwo Techniques for Compensating the Probe Positioning Errors in the Spherical NF–FF Transformation for Elongated Antennas
Two effective approaches for compensating the positioning errors in a near-field–far-field (NF-FF) transformation technique with spherical scanning for long antennas using a nonredundant number of data are presented. The transformation technique relies on the nonredundant sampling representations of the electromagnetic fields and on the optimal sampling interpolation (OSI) expansions, and assum...
متن کاملRadial Field Retrieval in Spherical Scanning for Current Reconstruction and NF–FF Transformation
In this paper, a near-field to far-field (NF–FF) transformation for the case of spherical scanning using equivalent magnetic currents (EMCs) and matrix methods is addressed. It is based on the decoupling of the field components and the iterative retrieval of the radial component of the electric field. The technique is applied for far-field calculation as well as for the estimation of the curren...
