Tolerance analysis of antenna arrays through Interval Analysis

Abstract

The analysis of the effects on the radiation pattern of the manufacturing tolerances of the control points (i.e., amplitude and phase weights) of antenna arrays is addressed. A strategy based on Interval Analysis (IA) is exploited to analytically compute upper and lower bounds of the power pattern as a function of the maximum deviations of the control point values from the nominal/reference ones. A set of representative results is reported to show the behavior of the IA-based tool as well as to assess its effectiveness.
