MI Technologies Demonstrates Helicoidal Measurement Technique at AMTA 2008

MI Technologies will feature an operational demonstration of a new and novel near-field scanning technique in the Clarendon Room during AMTA 2008. The new scanning method, referred to as helicoidal, is accomplished by scanning a surface similar to a helix about an antenna. The technique is based on research into non-redundant sampling methods performed by a team of professors at the University of Salerno in Italy.

The MI Technologies' Helicoidal measurement system consists of a linear vertical axis, an azimuth axis, position controller and a data acquisition system. By properly coordinating the simultaneous motion of these two axes, a helicoidal surface about the antenna under test can be accomplished. The primary advantage of the novel scanning technique is speed. By coordinating the motion of two simultaneous axes such that both axes are in motion simultaneously and by reducing the total number of data points to be acquired, the time to make a near-field measurement can be significantly reduced.

This theoretical method has been introduced in various technical papers published by researchers at the University of Salerno. This year at AMTA Dr Francesco D'Agostino will present a research paper on Wednesday, November 19 at 10:15 AM showing measured results comparing helicoidal scanning methods to classical cylindrical scanning methods. The paper is based on collaborative research between MI Technologies and the University of Salerno into new near-field acquisition techniques.
