learning outcome

After attending the lecture course, the students penetrate the fundamentals, applications, and trends in antenna engineering and its relation to ground-or satellite-based mobile communications, sensing, and signal processing. The students understand the theoretical foundations of antennas. They are able to explain how antennas function and can develop them as wave transformers, microwave systems (including feed and beam forming networks), and systems for spatial and spectral signal processing. The students can differentiate and apply types of elementary radiating elements, means to control and measure the radiation patterns, and approaches to employ antenna systems for signal processing (e.g., for MIMO applications). In the tutorials, in-depth examples of numerical problems in antenna design and simulation were covered and selected problems were treated in detail. Based on these skills and knowledge, the students present and discuss their own thoughts and solutions.

Upon having visited the shielded anechoic chambers as up-to-date research facilities (antenna measurement lab and Virtual Road - Simulation and Test Area), the students know how to perform antenna-related measurements.

The students have practiced and can apply in-depth theoretical and practical knowledge, identify highly relevant ongoing research activities, and can apply their soft-skills like time management, work planning, scientific reporting and presentation, and team work.

content

1. Wireless technologies: Brief introduction and example applications, propagation of electromagnetic waves: Free space vs multipath, requirements for antennas (receive and transmit)

2. Fundamentals of antenna engineering: Electrodynamic foundations, basic radiating elements, examples of practical radiating elements

3. Antenna arrays: Foundations of linear arrays, performance figures of linear arrays, beam forming and spatial signal processing

4. Practical aspects of antenna engineering: Packaging and protection, design and numerical simulation, antenna measurements

Practical studies cover, for instance, the following topics: patch antenna measurement with planar nearfield scanner, complex input impedance of a quarter wavelength monopole, network analyzer measurement, and two-way propagation between dipoles; part of the seminars address the use of formal and 3D electromagnetic full-wave computer simulation tools (e.g. MATLAB, CST, EMPro)
media of instruction

Development of contents using blackboard, supplementary illustrations using overhead transparencies (available in electronic form), electronic animations (where appropriate); problem solving for in-depth learning (problem sheet available in electronic form)
