AMTA Webinar Series
Title: Single-Cut Phaseless Near-Field Measurements
Speaker: Fernando Rodríguez Varel, PhD | Universidad Rey Juan Carlos | Madrid, Spain
Webinar Date: May 25, 2023 | 11:00 AM-12:00 PM (noon) Eastern Time

Abstract
Single-cut techniques allow for fast antenna characterization by measuring and transforming to far-field individual pattern cuts instead of the full sphere. The cut fields are expanded in a reduced set of cylindrical coefficients, which can be used to accurately compute the far-field in the main pattern cuts for antennas with separable aperture distributions. This presentation introduces several fast single-cut near-field to far-field transformation methods using amplitude-only data. This technique becomes a fast tool for antenna characterization when one is interested in a few cardinal plane cuts of the antenna and only magnitude measurements are available.
