3. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland3 INTRODUCTION Teaching is a noble and hard profession; To understand antenna courses : Very good teacher;

4. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland4 INTRODUCTION Excellent students; Or both.

5. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland5 INTRODUCTION We often use : Computer; excellent scientific software.

6. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland6 INTRODUCTION We can make these statement : Despite the excellent quality of the teacher : The course is not well assimilated; The content is not well understood. In the class all the students are not excellent; The graphical limitation of the blackboard; Things are making more easier by the use of computers and softwares.

7. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland7 INTRODUCTION We focus our energy on « Radiation and Antennas » course; The teacher can do ex-cathedra courses; But he will also use Matlab GUI to : Add more explanations; Draw more caracteristics; Calculate parameters;

8. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland8 PURPOSE To improve the antenna course; Construct different kind of exercices; Make an intellectual contribution of students to construct the course; Add more motivation by the use of ICT technology; Make more simulation on the web for student.

9. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland9 TRANSMISSION LINE THEORY Suppose that we have this antenna;

10. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland10 TRANSMISSION LINE THEORY We transforme it as a transmission line; We calculate the current distribution along the line;

11. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland11 TRANSMISSION LINE THEORY

12. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland12 METHOD OF MOMENTS

13. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland13 METHOD OF MOMENTS We need the geometrical description of the antenna;

14. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland14 METHOD OF MOMENTS The program calculate the current distribution along the antenna

15. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland15 METHOD OF MOMENTS We can after draw the radiation pattern

16. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland16 METHOD OF MOMENTS We did same thing with Yagi-Uda antenna.

17. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland17 ANTENNA CHARACTERISTIC PARAMETERS We can use the antenna formulas or the caracteristics calculated by the two others program;

18. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland18 ANTENNA CHARACTERISTIC PARAMETERS

19. International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland19 CONCLUSION We are building a Matlab toolbox which will contain all these programs related to the course; All these programs are suppose to be use in class while teaching; They will be available on the net for student homework; The first test will be next winter. We hope the students will enjoy it.
