Transmission lines (ability to solve standard problems); Basics of Radiation of EM fields; Basics of Antennas (definition of fundamental parameters); Basics of (wireless) Link budget.

- Introduction to antennas as system components - Antenna system parameters - Noiseless and Noise Link budget - Low and medium gain antennas for Broadcasting, Mobile communications, WiFi/WLAN, IoT (slot, patch, dipole) - Ultra-Wide Band (UWB) antennas - High-gain, reconfigurable and MIMO antennas (Arrays) with beamforming - Fixed beam - Scanning beam - MIMO

The Course is organized in two types of activities. 1- Lectures on the theoretical aspects and practical implementation issues (30 hrs), mainly carried on by instructors: topics will be approached from a more theoretical point of view, always referring to the application domain. 2- Activities mostly carried out by the students: a) solution of simple problems connected to the topics developed during lectures: the exercises are solved partially in class and partly at home and can require the development and the use of simple MATLAB scripts (15 hrs); b) numerical laboratories, in which some of the considered radiating systems, starting from the simplest components, are analyzed with dedicated software and experimental lab, in which they are experimentally characterized (15 hrs); c) optional: development of a project, consisting in the design, numerical characterization and measurements of a simple radiating system, for one of the considered applications. The course instructors are responsible for its manufacturing. The activity is carried on in small groups (2-4 people) or exceptionally also by a single student. The aim of this activity is to teach students to face a "real problem", learning to use a commercial tool for the numerical analysis of the component, and to discuss the effects of manufacturing tolerances and the possible discrepancies between computed and measured results.

The learning will be supported by handouts made available by the instructors, via the didattica web portal. 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;

A- Exam in standard form: written test on problem solving the test will propose problems similar to those assigned during the course, and questions on the lectures. It may encompass design of radiating elements, array factors, beam-forming networks or parts thereof. The test is closed-book (no material allowed), but useful formulas are provided with exam text (to avoid unnecessary mnemonic efforts); the formulas are taken from the course handouts. Duration: 2 hrs. B- Evaluation by grading of submitted assignments + oral discussion - Requires submission of all assignments, in complete form, by the indicated deadlines. The materials to be submitted include reports on the labs. - Assignments must be carried out individually (unless otherwise stated). - Oral discussion: discussion on the submitted assignments. In both cases A and B, the final score can be improved by the submission of a short report on the optional project activity 2c. One report for each group is required, to be delivered before the end of July's exam period. A maximum of 3 additional scores can be gained with 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.
