3. Patches, arrays and polarization (1 lab)

- We will use a near field scanner.

- You will learn:

• How to measure the radiation pattern of a patch antenna.

• How to tilt the angle of an array of patches.

• How to measure circular and linear polarization.

4. Refractive index and leaky waves (1 lab)

- You will learn:

• How to estimate the equivalent refractive index of a material.

• How to analyze the imaginary and real part of the wave numberof a leaky wave antenna; i.e. to characterize leaky waveantenna main parameters.


Laboratory (II)

5. Measurements of radiation patterns (1 lab)

- Ideally in an anechoic chamber.

- You will learn:

• What is an anechoic chamber.

• How to measure the radiation patterns.

• Differences between near- and far-field.


Laboratory (II)

Final project.

- It includes the literature review, design, simulation, manufacturing and testing.

- A list of projects will be uploaded after week 17.

• Alternatives can be proposed, but I have to accept the project before it starts.

- It will required a final report + oral presentation.

Evaluation of course

ILO of the course:

Students should, at the end of the course, be able to:

1. Explain the operation of a given antenna based on its geometry; and describe its

expected performance in terms of radiation pattern, efficiency, bandwidth, and

polarization.

2. Define the required specifications of an antenna for a given application.

3. Judge, by using physical constraints, if an antenna can fulfil some given

specifications.

4. Design an antenna for some given feasible and realistic specifications.

5. Simulate, evaluate the performance and design antennas using commercial

software: CST Microwave Studio or HFSS.

6. Measure the performance of an antenna by using standard microwave equipment.

The equipment includes vector network analysers, a spectrum analyser, a near-field

scanner, a signal generator and an anechoic chamber.

7. To find, understand and use relevant technical literature to solve antenna problems.

Evaluation:

• The students will be evaluated with:

• The attendance and participation in the labs.

• The attendance and participation in the lectures.

• Delivered reports of the results obtained in the labs.

• Delivered reports of the homework specified during the lectures.

Summary of the evaluation

14

- To pass the subject (grades D-E):

• Participate in the lectures.

• Homework has to be finalised and passed.

– Regularly, they must be delivered to the teacher.

– We will discuss the results in the lectures.

• Laboratories have to be finalised and passed.
