On the Modeling and Diagnosis of a Micro-Structured Wire Antenna System

Micro-structured systems of wire antennas the inter-element distance of which being much smaller than the electromagnetic wavelengths either in transmission or reception are studied by the authors from 3-D computational modeling to experiments in anechoic chambers on down-scaled prototypes. Recent results with focus on potential super-localization of a peculiar radiating element in the aforementioned micro-structure will be considered here while further challenges ahead, notably in terms of questions of super-resolved imaging in likewise microstructured structures will be sketched.
