Millimetre wave technologies and sensor solutions

VTT has been developing millimetre wave technologies for more than three decades. Our work covers a wide range of applications and industries from autonomous systems and robotics to public safety and healthcare. Exploring and developing unforeseen solutions together with our clients and partners continuously pushes the boundaries of existing technologies.

Our expertise in millimetre wave technologies

Holistic design of millimetre-wave systems ranging from 5G and 6G communications to imaging radars and cryogenically cooled receivers for radio astronomy.

Prototyping from component to system level using different MMIC technologies, antenna configurations and packaging technologies. 

Exceptional testing facilities for millimetre-wave components and circuits including reliability testing and space qualification.

Our service portfolio covers research and concept development as well as prototyping and testing of millimetre-wave components and systems for terrestrial, air- and spaceborne applications. We also have world-class facilities and infrastructure that meet even the highest standards. We host European Space Agency’s External Laboratory on millimetre wave technology, MilliLab, which helps the European space industry meet the demands of future millimetre wave missions.

Sensing solutions for demanding applications

Radars, which operate at millimetre waves, can provide 3D image-like information of the environment. Millimetre wave imaging radars have advantages over other imaging sensors such as cameras and LIDAR’s as they can operate also in demanding conditions such as in the darkness, rain, or in the fog. They have applications as perception sensors in cars, unmanned aerial vehicles (UAVs), and robotics, or as non-contacting sensors in health and well-being applications, where they can be used to monitor vital signs, such as breathing, heart rate, or heart rate variation. 

Millimetre wave technologies are an integral part of the next-generation 5G and beyond wireless networks and sensing solutions.

Trailblazing radar systems and imaging radiometers

New applications for advanced radar technologies are developed at an increasing pace. Our current 60 GHz FMCW frequency division multiplexing MIMO radar system uses VTT’s in-house designed SiGe MMIC front-ends. One of the advantages in VTT’s approach is that the solutions is scalable to extremely large aperture sizes effortlessly for high spatial resolution imaging. Another advantage is that it is capable for detecting and visualizing fast changes in the scene without image distortion.

New application areas include:

  • multi-person vital sign measurements
  • vibration mapping
  • people flow monitoring
  • autonomous robots
  • drones 

For imaging radiometers, we develop interferometric aperture arrays with custom SiGe MMICs, FPGA backends and waveguide feed systems that are fabricated with latest 3D printing techniques. This leads to low-cost, low power consumption and small size. They operate without mechanically scanning antennas, making them feasible payloads in UAV and cube sat applications.

Furthermore, VTT is a forerunner in developing silicon based SiGe and CMOS millimetre wave MMIC amplifiers for cryogenic operation.

Prototyping and testing services for millimetre technologies

We have unique research infrastructure for manufacturing and testing of millimetre wave components and systems. This allows us to support our clients through all phases of prototyping and testing. In our clean room laboratories, we have developed integrated passive device (IPD) and low temperature co-fired ceramics (LTCC) technologies that are suitable for integrating and packaging of millimetre wave systems. We have the equipment and expertise on assembling high frequency electronics using both flip-chip and wire-bonding methods. 

VTT has excellent high-frequency measurement capabilities and knowledge through MilliLab.

Our measurement capabilities cover:

  • micro and millimetre wave circuit characterization
  • dedicated systems for THz device characterization
  • measuring S-parameters on-wafer up to 220 GHz and off-wafer up to 700 GHz 
  • noise figures and spectrum analysis for both on- and off-wafer
