Electromagnetism, propagation, antennae, stealthness - 2019

Space antennas

For telecommunication, remote sensing radar & radio-navigation

OBJECTIVE :

This course presents a comprehensive overview of the wide variety of antenna systems used on satellites for telecommunication missions, observation (SAR radar) or radio navigation.

COURSE DURATION AND TIMETABLE :

The course lasts 4 days (32 hours), alternating presentations and some practical exercises (one on PC, designing an antenna for an actual space mission).

GENERAL APPROACH :

The training course is focused on:

  • a wide state of the art of what exists over the world
  • presenting design rules (and their practical application

through exercises) as concrete tools for designers, also enabling any participant interested in space systems to master the feasibility constraints of antenna subsystems and anticipate their performance.

PREREQUISITE :

Course Level:

This course is profitable for engineers mastering the basics of radio systems.

COURSE DIRECTOR(S) :

Gérard CAILLE:

Retired in January 2015 from Thales / Space Division (Thales Alenia Space France), where he was ‘Active Antennas expert’, and responsible for Advanced Antennas Research;

In collaboration with engineers from CNES and main industrial players in satellite domain.

This course is organised in partnership with SEE (Société de l'Électricité, de l'Électronique et des Technologies de l'information et de la communication), French branch of IEEE and main association of technical experts in electrical engineering field.
