Objectives
By the end of this course, students will:
- be familiar with the different types of antennas and their radiation principles,
- be familiar with the different fundamental parameters that characterize antennas,
- know how to study a link budget between two antennas (transmission and reception) (FRIIS formula),
- be able to size an antenna array (linear or planar) for a given set of specifications,
- be familiar with certain antenna simulation tools and characterization methods (measurement),
- be able to analyze a scientific article.
Description
This project is a PBL (Project-Based Learning) project.
It consists of two parts (Course & BE):
A- Course
- Introduction to radiation,
- Different types of antennas,
- Fundamental parameters,
- Link budget,
- Introduction to antenna arrays,
- Simulation tools and characterization methods (measurement),
- Introduction to the analysis of scientific articles.
B- Design office
- Analysis of a scientific article:
¤ Ability to reproduce the design of an antenna presented in a scientific journal (article) and understand how it works,
¤ Study the performance of this antenna in terms of adaptation and radiation.
- Reproduction of a “comparison & critical review” design:
¤ Ability to reuse this antenna by meeting specific specifications (different frequency band, different technology, etc.)
¤ Ability to adjust design parameters in order to modify performance.
- Networking of an elementary antenna:
¤ Ability to network an elementary antenna (1D linear and 2D planar) by setting the optimal inter-element distance (network mesh) for a given misalignment.
¤ Parametric study: impact of inter-element distance and number of elementary antennas (1D and 2D) on radiation performance (directivity, gain, array lobes, secondary lobes SLL, power and aperture efficiency, etc.).
- Drafting of a technical data sheet (design report)
