International Conference on Engineering Education July 25-29, 2005 - Gliwice, Poland Teaching Matlab Based Toolbox for Antenna Course Olivier Vidémé Bossou - Juan R. Mosig olivier.videmebossou@epfl.ch juan.mosig@epfl.ch SOMMARY INTRODUCTION PURPOSE TRANSMISSION LINE THEORY METHOD OF MOMENTS ANTENNA CHARACTERISTIC PARAMETERS CONCLUSION INTRODUCTION Teaching is a noble and hard profession; To understand antenna courses : Very good teacher; INTRODUCTION Excellent students; Or both. INTRODUCTION We often use : Computer; excellent scientific software. 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; TRANSMISSION LINE THEORY We transforme it as a transmission line; We calculate the current distribution along the line; TRANSMISSION LINE THEORY METHOD OF MOMENTS METHOD OF MOMENTS We need the geometrical description of the antenna; METHOD OF MOMENTS The program calculate the current distribution along the antenna METHOD OF MOMENTS We can after draw the radiation pattern METHOD OF MOMENTS We did same thing with Yagi-Uda antenna. ANTENNA CHARACTERISTIC PARAMETERS We can use the antenna formulas or the caracteristics calculated by the two others program; ANTENNA CHARACTERISTIC PARAMET
