Short Course Description

Antenna arrays are a key technology in several Electromagnetics applicative scenarios, including satellite and ground wireless communications, MIMO systems, remote sensing, biomedical imaging, radar, wireless power transmission, and radioastronomy.

Because of their wide range of application, the large number of degrees of freedom at hand (e.g., type, position, and excitation of each radiating element), the available architectures, and the possible objectives ranging from the standard radiation features (e.g.,maximum directivity, minimum side lobes, maximum beam efficiency) to the multi-physics constraints (e.g., power consumption, thermal diffusion and cooling, weight, robustness, tolerance/variantions vs atmospheric agents) until the more advances systemistic criteria (reconfigurability, multi-functionality, frequency-agility, wideband/wide-scanning, quantum properties/features, etc.), the synthesis of arrays turns out to be a complex task which cannot be tackled by a single methodology.
Despite a wide heterogeneity, most of the synthesis approaches share a common theoretical framework, which is of paramount importance for all engineers and students interested in such a topic.

The objective of the short course is therefore to provide the attendees the fundamentals of Antenna Array synthesis, starting from intuitive explanations to rigorous mathematical and methodological insights about their behavior and design. Moreover, recent synthesis methodologies will be also discussed with particular emphasis on unconventional architectures for complex communications and radar systems within a new optimality framework. More specifically, advanced methodologies and architectures will be introduced, and their application in the synthesis of linear arrays will be illustrated also with a set of "Hands on" software classes.
