Educational objectives
The course makes reference to the design of RF circuits to introduce the students to the knowledge of the basic principles and design techniques in modern RF and millimeter-wave wireless systems for aerospace with applications ranging from radar to telecommunications.
First degree in Engineering
Teaching methods
The course is organized as follows:
Classroom lessons on all subjects of the course;
Classroom exercises with the use of software suitable for solving electromagnetic problems.
Other information
The teacher provides teaching material to illustrate the lecture topics in detail
Learning verification modality
The exam provides an oral examination and possibly the presentation of a technical report.

The oral test consists of a discussion lasting about 30 minutes. Aimed at ensuring the level of knowledge and understanding acquired by the student on the theoretical and methodological content developed in the program. The oral test will also allow student to demonstrate communication skills with language ownership and autonomous organization.
