*Skills and abilities*

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

**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.
