Power pattern sensitivity analysis of reflectarray antennas to substrate uncertainties through the minkowski interval analysis

Abstract : 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 (7A)-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 IAMS method provides narrower and more reliable bounds than the IA-CS.
