Antennas Graziano Cerri
Knowledge of ordinary and partial derivatives differential equations of the first and second order. Knowledge of curvilinear, surface and volume integrals. Knowledge of divergence, gradient and curl operators. Elements of electromagnetic wave propagation.
KNOWLEDGE AND UNDERSTANDING:
The course provides elements to understand different antenna families on the base of their electromagnetic characteristics, their performances, allowing also to make choices and comparisons on the base of their use and to develop design procedures for realization of new radiating systems. Mathematical models to characterize the radiation phenomena and wave propagation will be provided as well. This knowledge, as well as elements concerning the disciplines of the Laurea Magistrale, aimed to provide a high expertise of modern technologies, adopting methodologic tools to formulate and solve different problems of the Electronic and Telecommunication Engineering, both at the analysis and design stage, and during realization and testing of the final product, where the radiating system is a significant partCAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
In order to face problems related to antennas, also in complex environments, the student has to understand correctly problems of analysis and design of radiating structures, and problems related to the propagation of electromagnetic waves in the ionosphere, in the troposphere, and in urban environment. This means: capability for application of techniques to evaluate radio coverage in realistic environments; capability to carry out measurements critically explained; capability of choice of suitable techniques to design antennas satisfying proper constraints also for use in new, high tech, and emerging contests; capability of applying methods to realize radio linksTRANSVERSAL SKILLS:
Some measurements carried out in laboratory and concerning significant canonical situations, previously described theoretically in the classroom, will lead to the development of technical reports. The aim is to improve the general autonomous judgement, to better the capability to relate with other students, and to develop the critical learning process. Connections with aspects typical of disciplines concerning Electromagnetics, Electronics, and Telecommunications will provide a wide band expertise to the student to be used both in the ICT contest and in other not ICT industrial contests, that use technologies based on electromagnetic fields

1) depending on the number of attending students, and considering the availability of only one measurement set-up, laboratory sessions will be carried out, but it is impossible to quantify this activity in terms of hours.
2) numerical exercises will be carried out during lessons as integral part of the course aimed to better understanding theoretical and design aspects.
3) a detailed program is available at the teacher web site with cross reference to text books
Development of the examination
LEARNING EVALUATION METHODS
The exam is oral. It consists of three questions. The first has a practical feature and consists of the soluton of a test case or a simple design. The second concerns theoretical aspects related to antenna modeling. The third regards propagation of electromagnetic waves aimed to the design of a radio link.
LEARNING EVALUATION CRITERIA
The student has to show his understanding and his capability to handle the fundamental aspects characterizing antenna theory and electromagnetic wave propagation, adopting proper methods to state, approach, and solve autonomously the different problems.
LEARNING MEASUREMENT CRITERIA
It is related to the autonomy of the student to approach the proposed problems, to the correct methodologic approach, and to the discriminating capability to choose the most proper solution.
FINAL MARK ALLOCATION CRITERIA
The three exam questions have equivalent weights. The highest mark cum laude is given if the student shows total autonomy, a rigorous methodologic approach, a great critical sense. The minimum score of eighteen over thirty is given when the student shows sufficient autonomy and sufficient knowledge of the most important antenna aspects.
