Facility News

Here is some of the latest news of what has been happening at the UKRI National Millimetre Wave Measurement Facility.


In January the UKRI National mmWave Measurement Facility had its open day and Networking event. It was a great day and thank you to all the visitors who joined us. We had a total of 56 Guests from various companies and universities around the country, including Cambridge and Edinburgh.

We hope you had a good day, and we especially want to thank Prof. Jon Willmott and his research group for giving tours of their lab and explaining how they can print mmWave planar antennas on their Optimec printer. This attracted a lot of interest.

There was also exciting news from Prof. Tim O’Farrell as he announced he had just gained funding for a new 6G sub-THz SDR measurement facility in Sheffield.

I had a lot of interesting conversations with attendees and it is clear that the wider research and commercial community is becoming increasingly active in mmWave systems

Attendees were very interested in what they saw and several asked if we would be running the event again next year

In January there has been some exciting news released about measurements take at the National mmWave Measurement Facility. Some printed antennas designed and printed at the University of Sheffield and measured in our facility, have shown performance that matches those produced using conventional manufacturing techniques. You can read more about this in the University of Sheffield's Department of Electronic and Electrical Engineering news page linked below.

Networking and Open day!

We are having a Networking and open day on Friday 20th January 2023!

This is a networking event for people working in the area of millimetre antennas, circuits and systems. You can tour the facility and network with academics, researchers and companies working in the mmWave area. There will also be talks from Innovate UK, DASA and other key research funders to explain how you can apply for funding to support your activities. 

You can register for the event on eventbrite here

Please can fill out the form below with your dietary requirements and areas of interest, this will help us make sure you get the most out of the day.

You are welcome to bring along a poster or something to display to help explain and advertise your work if you wish to.

We hope you can make it to our open day, if you have any questions please contact the facility.

In Novemeber the National mmWave measurement facility was used by Eddie Ball & Sumin David Joseph to perform some initial measurements of three different GaAs mmWave integrated circuits at 73 GHz they have designed. The circuits were made by United Monolithic Semiconductors as part of a GaAs multi-project wafer. Initial lab tests of RF performance have shown good results. Probing used two MPI DC probe cards and our VNA with VDI WR15+ frequency extenders and 150 micron GSG PicoProbes. Circuits for VCOs and antenna array beam steering have been prototyped, with more testing to follow. The circuits are part of Eddie’s UKRI Future Leaders Fellowship in mmWave Transceivers.

In October Dr Stephen Henthorn has been using the facility in his research into metasurfaces, below is a quote from him and some images of his research.

I've been using the mmWave facility to measure metasurfaces at frequencies from 30 GHz to 100 GHz. Metasurfaces allow us to control how electromagnetic energy reflects off and transmits through surfaces by designing their structure, rather than relying on their chemistry. We can choose patterns of metal on a surface to produce the magnitude and phase response required at different frequencies, and in advanced forms we can get exotic effects like bending microwaves in unexpected directions, or breaking symmetry by letting waves through in one direction, but not the other. It's expected that metasurfaces in the mmWave range will have applications in 6G mobile communications, such as improving antennas and radio transmitter efficiency, and producing intelligent surfaces which can direct beams of energy to our phones. The facility and technicians have been very helpful, using the PNA-X Vector Network Analyser with VDI frequency extenders to measure reflectivity and transmission through the metasurfaces, and constructing test rigs to ensure repeatable and reliable measurements.

In July we had a visit from the UTC Sheffield Physics class, it was great to meet them and explain what we do here at the National mmWave Measurement Facility.

This month we have a new user of the National mmWave facility, Mr Meshari Alanazi, we look forward to working with you.

I am a PhD student working on the efficient design of mmWave dielectric resonator antennas. The designed antennas operate at the 28 GHz, 40 GHz and 60 GHz frequency bands with excellent agreement between simulations and measurements using the mmWave facility.

In June we had a visit from Dr Sergio Rodriguez-Albarran, the first ever user of the National mmWave Facility. It was great to see him on his graduation day.

I’m honoured to have been the first ever user of the cutting-edge National mmWave facilities in the University of Sheffield back in late 2019.

My project was about exploring tunable materials in dielectric resonant antennas (DRAs) at mm-Wave typical frequencies (24 -26 GHz) the resonators I studied were 3D-Printed in Polylactic Acid (PLA) and filled with graphene oxide gel, which, in presence of an incident biasing voltage achieved electronic tunability in the desired frequency range. The involvement of the innovative equipment was crucial in obtaining the frequency response, reflection coefficient and both 2D and 3D radiation patterns of all the antennas I designed constructed and characterised in my last chapters of the Thesis I presented to obtain my PhD degree in March 2020.

In February we had a visit from Ming Yang and Ryan Fairclough from Arralis to test their antenna design on our NSI spherical measurement system.
