INTRODUCTION

Teaching is a noble and hard profession; To understand antenna courses :

Very good teacher;

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 4

INTRODUCTION

Excellent students; Or both.

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 5

INTRODUCTION

We often use : Computer; excellent scientific software.

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 6

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.

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;

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.

TRANSMISSION LINE THEORY Suppose that we have this antenna;

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 10

TRANSMISSION LINE THEORY We transforme it as a transmission line;

We calculate the current distribution along the line;

METHOD OF MOMENTS

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 13

METHOD OF MOMENTS

We need the geometrical description of the antenna;

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 14

METHOD OF MOMENTS

The program calculate the current distribution along the antenna

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 15

METHOD OF MOMENTS

We can after draw the radiation pattern

METHOD OF MOMENTS

We did same thing with Yagi-Uda antenna.

International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland 17

ANTENNA CHARACTERISTIC PARAMETERS

We can use the antenna formulas or the caracteristics calculated by the two others program;

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.
