520 $a The simulated Near-Field of a radiating array is analysed in depth. A formulation and a procedure to correct the spectral domain of the field are established.
520 $a The technique developed is applied to experimental and simulated Near-Field data of large radiating Antennas leading to new information about the accuracy and speed of measurement achievable.
520 $a This thesis examines the possibility of increasing the speed of Near-Field measurement of an Antenna, by reducing the number of measurement points and by determining the degree of truncation permissible while maintaining a prescribed degree of precision of the reconstructed far-field.
520 $a The mathematical formulation leading to the near-field to far-field transform is presented in a novel and simpler form to use. Relations are established between the selected area and sampling rate of Near-Field measurement and the accuracy of the Far-Field of an Antenna. The spectral domain of the field is analysed in each case and parametric curves are derived. Correction of the spectral domain can significantly improve the accuracy of the Far-Field while using the same amount of Near-Field data.
520 $a A new concept, described as the Signature Function, is presented, analysed and tested. This new concept offers the possibility of conducting a highly reduced set of measurements while producing accurate results for antennas whose “Signature Function” is previously determined or can be estimated.
