About High-Int

High-Int is a Vinnova project, funded under the Smartare Elektroniksystem framework.

Wireless communications are rapidly evolving. In particular, users are demanding new services in the present networks that require of higher data transfer. The new generation of mobile communications, 5G, started to be deployed at the end of 2019. However, 5G will only cover the present needs of the users. Further research to increase the rates of wireless communications is needed now to cover the expectations in a near future. Since most of the low frequency spectrum is already crowded, the only possibility is increasing the operational frequency where narrow bands permit larger data transfer and short delays.

High-Int will enable a complementary cooperation between both Ericsson and KTH. KTH has experience in the development of innovative antenna solutions, typically fully-metallic antennas based on the concept of lenses and leaky-waves, and Ericsson AB is a leading technology-driven company in telecommunications.

  • Participants:

    At High-Int, we have participants from KTH Royal Institute of Technology, and Ericsson AB. The participants at KTH are located in Stockholm, while those of Ericsson are in both Kista (Stockholm) and Lindholmen (Gothenburg). We include senior and senior researchers, aimed to an adequate gender balance.

  • Workshops:

    Every year, we organize a workshop. This workshop is aimed to exchange ideas between our partners, and to define the new lines of research to be followed. The next High-Int workshop is expected to be held in Stockholm on June 2020.

Intended antenna designs:

In High-Int, we will develop innovative integrated antennas at millimetre waves. At these frequency bands, antennas are a critical part of the communication system. Specifically, antennas must be highly directive and to provide a high radiation efficiency. Therefore, new antenna configurations are needed to overcome these challenges. These antennas must be fully-metallic, so the propagation is only in air ensuring a high efficiency. Moreover, they need to integrate multiple functionalities to reduce the losses in transitions between components.
