- Contents
- Introduction to Antennas and Receiving Radiation Mechanisms. Study of wire antennas. Aperture antennas and arrays. Examples of design and measurement of antennas.
- Reference texts
- R: E: Collin, Antennas and Radiowave Propagation (Mcgraw Hill Series in Electrical and Computer Engineering)
- Educational objectives
- Understand physical phenomena related to antennas in order to provide a unified view of methodologies to address the study of various classes of antenna systems for research and project purposes in telecommunication and aerospace applications.
- Prerequisites
- 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; Laboratory exercises.
- 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.
