### Course description

Knowledge and understanding.
The student must demonstrate knowledge and understanding of:
b) standard definitions of terms and symbols to be used for antenna description.

Ability to apply knowledge and understanding.
The student must demonstrate ability to apply fundamentals of electromagnetic radiation to analyze the properties of
a) some elementary antennas (wire antennas, planar antennas);
b) some antenna structures (1D arrays and 2D arrays).

Autonomy of judgement.
The student must demonstrate to address independently the analysis of the main properties of an antenna

Communication skills.
The student must demonstrate to clearly describe technical issues.

Learning skills.
The student must demonstrate to be able to integrate information coming from different sources and relevant to the analysis of antennas’ properties.

### Learning assessment

Oral examination, about one hour long, aimed at verifying that:

- the student knows
b) standard definitions of terms and symbols to be used for antenna description;
(mandatory to pass the examination)

- the student is able to apply the fundamentals of the electromagnetic radiation to analyze the properties of
a) some elementary antennas (wire antennas, planar antennas);
b) some antenna structures (1D arrays and 2D arrays).
(mandatory to pass the examination)

- the student is able to address independently the analysis of the main properties of an antenna;

- the student is able to clearly describe technical issues;
(mandatory to pass the examination)

- the student is able to integrate information coming from different sources and relevant to the analysis of the antennas’ properties.

The examination consists of a discussion based on two questions.
