%T Introduction to Interval Arithmetic applied to Antenna Array Analysis
%U http://www.eledia.org/students-reports/694/
%X Errors and imperfections characterize almost every implementation of real physical devices. In an antenna array, elements' excitations values with are usually affected by errors due to imperfections on the feeding network components. This leads to implement an antenna radiating a pattern that generally differs from the expected one. In this framework, this report is aimed to introduce a novel methodology based on Interval Arithmetic aimed to calculate an upper and lower bounds on the power pattern given the interval tolerance of the amplifiers and of the phase shifters connected to the radiating elements. The power pattern features have been also defined exploiting the Interval Arithmetic tool, as well.
