Advanced antenna techniques and measurements

• apply electromagnetic field theory to analyze antennas.
• calculate/compute the radiation from several types of antennas and determine parameters such as directivity, gain, and polarization.
• understand and apply integral equation method and MoM on primarily wire antennas.
• understand and analyze microstrip antennas, and aperture antennas including horn and reflector antennas, and concepts related to small antennas and superdirective antennas.
• understand and analyze antenna arrays, including phased arrays.
• understand and apply array pattern synthesis.
• develop simple computer codes for the analysis of antennas.
• apply commercial computer codes for the analysis of antennas.
• explain, compare, and assess different methods for measurement of antenna radiation – in particular far-field measurements, planar near-field measurements, and spherical near-field measurements.
• understand and explain the theory for planar and spherical near-field measurements.
• carry out measurements of antenna radiation with different antenna measurement systems in DTU’s Electromagnetic Test Centre (ETC).
• analyze and compare calculated and measured results and explain possible differences.

30410/30428, The course requires knowledge of fundamental antenna theory and advanced electromagnetics as contained in the prerequisite courses or similar courses. Courses on applied mathematics and numerical methods are an asset.

Lectures, exercises, and project

The course provides a strong background for special courses and master’s thesis projects in antennas and applied electromagnetics.

A minor portion of the course may vary from year to year to reflect relevant ongoing research within the field.
