Objectives
This course aims to acquaint students with fundamental concepts of electromagnetic radiation, which are necessary to understand antennae. Covered will be the basic principles of antennae, their most important characteristics with a particular reference to filiform antennae and group of antennae.
In the final part of the course wave propagation in free space between antennae it will be covered.
During the semester it will be used an antenna simulation program and antennae in anechoic chamber will be measured.
Program
Introduction to the basic theory of radiation and antennae; fundamental parameters of antennae; filiform antennae: their relationship with infinitesimal dipole; half wavelength dipoles; earth effect over fundamental antenna characteristics; ring antennae; group of antennae and their properties: analysis and synthesis of radiation diagrams and Fourier method.
Aperture antennae: radiation equations and design; the most important types of aperture antennae and reflector antennae. Wave propagation in free space 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 mark
Exam: 60% of the final mark. Students have to reach a minimum mark of 7 out of 20 to complete the course.
Examinations or Special Assignments
Students with a special status have to complete the continuous assessment component with a minimum mark of 7 out of 20. Students can ask for permission to use the laboratory, if necessary.
Classification improvement
If students take an exam to improve their mark, it will only be taken into account the mark of that exam (from 0 to 20).
Observations
Exams which take place at the special season may consist of an oral exam.
