Welcome to Satellite Communication Systems

Description: Satellite communication industry is growing rapidly, as evidenced by a number of evolution trends such as the increase in Nano-satellites, the utilization of low-Earth orbit (LEO), bew application cases for 5G and the Internet of Things (IoT), as well as the efforts on reusable rocket launch vehicles. To address the new requirements emerging during the evolution the satellite communication system is facing significant challenges we never experienced before.

This course aims to deliver knowledge about the fundamentals and the state-of-the-art design technologies for satellite communication systems, especially for small satellites. The course will cover three main topics:

Overview and satellite communication systems - APMS, GomSpace
Orbit design, link budget
Deployable architectures
Satellite subsystems
Transceivers and electronics for satellite communications - APMS
Transceiver fundamentals
PA, LNA, Mixer, Filter, Modulator
Antennas for small satellites - APMS, SpaceCom
Antennas fundamentals
Beam-steerable arrays
Deployable antennas
Prerequisites: Basic circuit theory, antenna theory, basic physics, basic knowledge on wireless communication systems, elementary knowledge on satellites.

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.

Welcome to Electromagnetics

Description: This course should provide the PhD candidates in the Wireless program the necessary background on the physical aspects of radiowave communication. The motivation follows the well-known fact that students in this program come from various backgrounds, often specialized in communication protocols and information theory, but lacking the necessary physical insight into electromagnetic fields, antennas and radiowave propagation. For the rest of the participants, this course should give a recapitulation of the previously acquired knowledge and extending it to meet the needs of their dissertation, as many of them will need to design an antenna and/or carry out electromagnetic simulations in their projects.



The course has been run 4x before, every two years:

In the 2011 run, the course has been attended by 8 participants, with above average rating and evaluating the course content as relevant.
In 2013 there were 10 participants: the rating and content evaluation was, with one exception, above average.
In 2015 there were 10 participants: the overall rating was strongly above average and content relevance was slightly above average.
In 2017 there were 12 participants. The overall rating was very good and content relevance evaluated as excellent.
In the next run, slightly less than 10 participants are expected to join, if the course is held already in spring.
