Academic Year 2020/2021

Learning outcomes

The aim of the module 1 is to provide the students with the fundamental knowledge to recognize and understand problems related to the distribution of signals in complex environments, where other sources can influence and disturb its reliable transmission. Filtering and shielding techniques for conducted and radiated disturbances will be discussed, together with the measurement methods required by the main International and National EMC Directives. The module 2 aims to provide the basic knowledge needed to understanding operating principles, design skills-set and installation constraints of antennas and radar systems for automotive applications, such as broadcast, inter and intra vehicle communications, and anti-collision systems for safety and autonomous driving.

Course contents

Teaching methods

Presential lectures covering theory and exercises.

Assessment methods

The exam aims at assessing the student's knowledge and skills in the course topics and it consists of two independent oral parts (Part 1: Module 1 + Module 2; Part 2: Module 3).

NOTE: For all matters regarding exam regulations one should refer to Regolamento Didattico di Ateneo. Especially relevant is Art. 16 (5: positive grades are written on the official record; 7: negative grades are also written on the official record, and they do not have an impact on the student's GPA; 8: one cannot retake a passed exam once its grade has been written on the official record).

Teaching tools

Lecture slides will be made available before class.

A limited number of copies of the adopted textbooks and other relevant textbooks are available at the library.
