Power Pattern Sensitivity Analysis Of Reflectarray Antennas To Substrate Uncertainties Through The Minkowski Interval Analysis
2017 INTERNATIONAL APPLIED COMPUTATIONAL ELECTROMAGNETICS SOCIETY SYMPOSIUM - ITALY (ACES)(2017)
摘要
In this work, the effect of the fabrication uncertainties on the substrate thickness on the radiation performance of the reflectarray antenna is addressed. An interval analysis (IA)-based method is used to compute the upper and lower bounds of the power pattern as a function of the deviations in the substrate thickness. The Minkowski Sum (MS) is exploited to combine interval phasors in order to mitigate the over-estimation of the power pattern bounds affecting standard Cartesian IA (IA-CS) techniques. A representative numerical example shows that the proposed IA-MS method provides narrower and more reliable bounds than the IA-CS.
