Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to describe the properties of the far field
• be able to use the relation between directivity and effective antenna area
• be able to explain Friis´ transmission formula and the radar equation
• be able to give account for the properties of some common types of antennas
• be able to outline the theory of array antennas
• be able to interpret antenna problems as integral equations and understand the basics of their numerical solution

Competences and skills
For a passing grade the student must

• be able to calculate the far field for a given antenna current
• be able to calculate the power transmitted from a transmitting antenna to a receiving antenna
• be able to calculate the antenna pattern for a group antenna
• be able to perform pattern synthesis
• design, simulate and measure a patch antenna
• make a written account for the laboratory work

Judgement and approach
For a passing grade the student must

Contents

Radiation integrals. The far field. Antenna parameters. Friis´ transmission formula. The radar equation. Various antenna types such as wire antennas, patch antennas, aperture antennas, array antennas including pattern synthesis, reflector antennas, measurement techniques. Numerical methods for antenna problems, e.g., the method of moments.

In the laboratory work part a patch antenna is designed, manufactured and measured.
