L'insegnamento di Wireless Access Electromagnetics svolge nell’a.a. 2026/27 una sperimentazione didattica per l’attivazione di un Nuovo Modello Formativo; gli/le studenti riceveranno informazioni dettagliate nella prima lezione dell’insegnamento

The course is organized into two main types of activities. 1. Lectures Lectures (30 hours), mainly delivered by the instructors, cover both the theoretical foundations and the practical implementation aspects of radiating systems and antennas. The topics are presented from a rigorous theoretical perspective while maintaining a strong connection with real-world applications, including wireless communication systems, satellite platforms, aerospace technologies, and emerging sensing infrastructures. 2. Student-centered activities A significant part of the course is devoted to activities carried out directly by the students: a) Exercise sessions (15 hours) Students solve problems related to the topics introduced during the lectures. Exercises are carried out partly in class and partly as homework assignments, and may include the development and use of simple MATLAB scripts for the analysis and design of radiating systems. b) Numerical and experimental laboratories (15 hours) Laboratory activities focus on the analysis, simulation, and characterization of radiating systems, starting from basic antenna components up to more advanced configurations relevant to communication and aerospace applications. Numerical laboratories employ dedicated commercial software tools, while experimental laboratories involve the measurement and characterization of antennas and radiating devices, including testing and measurements carried out in an anechoic chamber. c) Optional project activity Students may also participate in an optional group project involving the design, numerical analysis, fabrication, and experimental characterization of a simple radiating system for one of the applications considered during the course. The course instructors are responsible for the manufacturing of the prototypes. The activity is carried out in small groups (typically 2–6 students). The objective of the project is to provide students with experience in addressing a realistic engineering problem, including the use of professional simulation tools, the interpretation of experimental measurements, and the evaluation of manufacturing tolerances and discrepancies between simulated and measured results.

The learning will be supported by handouts made available by the instructors, via the didattica web portal. The material also includes a collection of solved exercises, whose solution is discussed during classes. Other materials, and relevant sources will also be made available. The provided handouts are all that it is needed for preparing to the final exam. Further bibliographical indications will be given at the starting of the Course.

Exam: Written test; Compulsory oral exam;

The main objective of the exam is to assess the students’ understanding of the course topics, including the knowledge of the principal classes of radiating systems adopted in modern wireless, satellite, and aerospace applications; the ability to identify the requirements and constraints of radiating systems in relation to their operational environment; the capability to apply appropriate techniques and dedicated software tools for the analysis and design of antennas and radiating systems. The exam may be taken according to one of the following two modalities. A – Standard exam format: written problem-solving test The written test consists of problems similar to those assigned during the course. The exam is closed-book: no notes, books, or other materials are permitted. However, the formulas required for solving the exercises are directly provided within the exam text and are taken directly from the course handouts. Duration: 2 hours. B – Continuous assessment through assignments and oral discussion This modality requires: - participation in a welcome test administered at the beginning of the course (the result of this test does not contribute to the final grade); - individual submission of all assignments by the specified deadlines; - submission of lab reports and related materials. Assignments and lab reports must generally be completed individually (unless otherwise specified) and must include the developed scripts and a discussion of the results obtained either numerical or through measurements. The assessment is completed through an oral discussion mainly focused on the submitted assignments, lab activities, and the related theoretical aspects. The maximum grade achievable with the exam in both the modalities is 30/30 with laude. Optional project activity In both modalities A and B, the final grade may be improved through the submission of a short report on the optional project activity described in Section 2c. The project may involve the design, simulation, fabrication, and experimental characterization of a simple radiating system. One report is required for each project group and must be submitted before the deadlines communicated by the instructor at the beginning of the course. A maximum of 3 additional points may be awarded through this activity.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
