Planar Near-Field Antenna Measurements Using Nonideal Measurement Locations¤
The standard planar near- eld to far- eld transformation method requires data points on a planerectangular lattice. In this paper we introduce a transformation algorithm in which measurements are neither required to lie on a regular grid nor are strictly con ned to a plane. Computational complexity is O (N logN), where N is number of data points. (Actual calculation times depend on the numeri...
متن کاملNear-Field Antenna Measurements Using Nonideal Measurement Locations
|We introduce a neareld to fareld transformation algorithm that relaxes the usual restriction that data points be located on a plane-rectangular grid. Computational complexity is O (N logN), where N is the number of data points. This algorithm allows e cient processing of neareld data with known probe position errors. Also, the algorithm is applicable to other measurement approaches, such as pl...
متن کاملCylindrical/Spherical Near-Field Antenna Measurement System
A low-cost, fully operational cylindrical and spherical near-field antenna measurement system designed, built, and programmed by a University of Rhode Island Capstone team is presented. The goal of this project was to modify an existing planar near-field system and apply new processing techniques to extract the far-field patterns of an antenna under test (AUT) of any physical shape. The aim of ...
متن کاملTechniques for Reducing the Effect of Measurement Errors in Near-field Antenna Measurements
The NIST 18 term error analysis has been used for some time to estimate the uncertainty in the far-field antenna parameters determined from near-field measurements. Each of the error terms is evaluated separately to estimate the uncertainty it produces in parameters such as gain, directivity, side lobe level, cross polarization level and beam pointing angle. This identification and evaluation o...
متن کاملRange Multipath Reduction in Plane-polar Near-field Antenna Measurements
This paper details a recent advance that, for the first time, enables the Mathematical Absorber Reflection Suppression (MARS) technique to be successfully deployed to correct measurements taken using plane-polar near-field antenna test systems with reduced AUT-to-probe separation. This paper provides an overview of the measurement, transformation, and post-processing. Preliminary results of ran...
