Objectives

1- BACKGROUND
Communication engineers need to have a good understanding of the basic principles behind antennae design and performance, as well as their integration in communication links. In order to achieve this goal it is necessary that the students have solid prerequisites in Electromagnetic Theory and Wave Propagation.

2- SPECIFIC AIMS
This course aims to familiarize the student with fundamental concepts of electromagnetic radiation, which are necessary to understand antennae. The basic principles of antennae and their most important characteristics are covered, with emphasis on wire antennae and arrays.
Also covered in this course are aperture and reflector antennae.
Towards the end of the semester, wave propagation between antennae, in free space, are studied.
During the semester an antenna simulation program is used and some antennae measurements in an anechoic chamber are performed.

3- PREVIOUS KNOWLEDGE
Fundamental courses in Electromagnetic Theory and Wave Propagation.

4- PERCENT DISTRIBUTION
Scientific component: 70%
Technological component: 30%

5- LEARNING OUTCOMES
After attending this course, the student will have a solid knowledge and understanding of the following areas: antenna design and analysis, signal propagation between antennae and integration of antennae at the system level.
Beyond the theoretical presentations, the student uses a specialized computer program dedicated to antenna simulation and also makes some antenna measurements, using an anechoic chamber.

Program

Introduction of the basic theory of radiation and antennae.
Fundamental parameters of antennae; wire antennae: their relationship with the infinitesimal dipole. Half-wavelength dipoles. Earth effect and its impact on fundamental antenna characteristics.
Ring antennae, group of antennae and their properties: analysis and synthesis of radiation diagrams. The Fourier method.
Aperture antennae: radiation equations and design; the most important types of aperture antennae and reflector antennae. Wave propagation between antennae.

Eligibility for exams

Students have to reach a minimum mark of 7 out of 20 in the continuous assessment component.

Calculation formula of final grade

Continuous Assessment: 40% of the final grade.
Final Exam: 60% of the final grade.
Note: The composite final grade is only valid if the student obtains at least 7 (out of 20) in the Final Exam.

Examinations or Special Assignments

Students with a special status have to complete the Continuous Assessment component with a minimum grade of 7 out of 20. Students can ask for permission to use the laboratory, as needed.

Classification improvement

If the student has already passed the course and opts to take an exam to improve the grade, taken into account will only be the grade obtained in that exam (from 0 to 20). In other words, the Continuous Assessment component is no longer taken in consideration.

Observations

Exams which take place during the special season may consist of an oral exam.
