Our goal is to be world-leading in the following areas:

  • Modular solutions with low power consumption for wireless sensor networks. 
  • Wireless data transmission with focus on high data rate but at low cost.
  • Antenna and radio frequency (RF) design for broadband and multi-band communication systems.

Innovate

Our research in Communication Electronics has the purpose to invent technical solutions for future wireless systems of high frequency and high data rate, while reducing power consumption and cost. We wish that our research results would contribute to the social development of a green world in the future, e.g., Smart Cities utilizing extensively wireless and digital technologies.

Inspire

Our teaching in Wireless Systems has the purpose to inspire undergraduate and postgraduate students with state-of-the-art knowledge of modern communication technologies. After learning our well-planned courses, you will be powered with the required knowledge for developing of wireless communication systems.

Research activities

Smart city – wireless sensor networks and cloud services

With the aid of the Internet of Things technology it is possible to measure, regulate and even send alerts for monitoring of carbon dioxide levels, particulates, temperature, humidity, levels of volatile organic compounds, vibrations in a bridge...

Wireless sensor network with green wall to improve indoor climate

We use our developed wireless sensor network to monitor and control green walls with different kinds of plants in one of our laboratories, to measure, e.g. CO2 and particular levels.

Advanced techniques for GHz-frequency synthesizers

This research aims to improve the traditional frequency synthesizer architecture, using advanced calibration routines, improved modeling and noise suppression techniques such as sub-sampling.

Teaching activities

Wireless Systems profile

We are responsible for the Wireless Systems profile within the Electronic Design (ED) program. Our goal is to inspire students with the state-of-the-art of wireless communication electronics. 

After learning the courses in this profile, you will be powered with knowledge of radio frequency (RF) and microwave circuit design, antenna theory and design, digital communication electronics, and wireless sensor networks, etc. 

We are also highly engaged in the entire ED program giving modern courses from the first to the last year. Much of the knowledge is directly related to our research activities in the Communication Electronics research group. Some given courses are listed below. 

  • Digital Communication Electronics, TNE064
  • Analog/Digital System Design, TNE026
  • RF Circuit Design, TNE088
  • RF System Design, TNE062
  • Wireless Sensor Networks, TNE090
  • Microwave Engineering, TNE071
  • EMC and PCB Design, TNE 089
  • Antenna Theory and Engineering, TNE083

Laboratories

PCB-labbet på Campus Norrköping

Printed circuit board laboratory

The printed circuit board (PCB) laboratory has been in use since November 2001. It is used for both research and course projects. We can produce professional double sided through-hole plated PCB-boards up to 210 x 300 mm.

Radio frequency measurement laboratory

The radio frequency (RF) measurement laboratory is equipped with signal generators, spectrum analyzers, vector network analyzers and oscilloscopes, etc.

Electromagnetic compatibility laboratory

Electrical and electromagnetic noise sources become more and more common as the number of advanced electronic equipment increases. Electromagnetic compatibility (EMC) aims at measurement of unwanted emissions from electrical equipment.
