SOMMARY

• INTRODUCTION
• PURPOSE
• TRANSMISSION LINE THEORY
• METHOD OF MOMENTS
• ANTENNA CHARACTERISTIC PARAMETERS
• CONCLUSION

3
INTRODUCTION

• Teaching is a noble and hard profession
• To understand antenna courses
• Very good teacher

4
INTRODUCTION

• Excellent students
• Or both.

5
INTRODUCTION

• We often use
• Computer
• excellent scientific software.

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.

7
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
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
TRANSMISSION LINE THEORY

• Suppose that we have this antenna

10
TRANSMISSION LINE THEORY

• We transforme it as a transmission line
• We calculate the current distribution along the
  line

11
TRANSMISSION LINE THEORY
12
METHOD OF MOMENTS
13
METHOD OF MOMENTS

• We need the geometrical description of the
  antenna

14
METHOD OF MOMENTS

• The program calculate the current distribution
  along the antenna

15
METHOD OF MOMENTS

• We can after draw the radiation pattern

16
METHOD OF MOMENTS

• We did same thing with Yagi-Uda antenna.

17
ANTENNA CHARACTERISTIC PARAMETERS

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

18
ANTENNA CHARACTERISTIC PARAMETERS
19
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.
