Predicting antenna pattern degradations in microstrip reflectarrays through interval arithmetic
IET Microwaves, Antennas & Propagation(2016)
摘要
The effects on the antenna power pattern of the tolerances in etching the microstrip patches and in the knowledge of the substrate characteristics of reflectarray antennas are predicted with an approach based on the arithmetic of intervals and the interval analysis (IA). The uncertainties on the geometric and electric antenna parameters are defined as intervals and the rules of IA are applied to d...
