Research Topics
Below you will find the most important lines of research in which we are working or have been working in our research laboratory throughout the years.
Materials Characterization
Custom test solutions for electromagnetic characterization of materials (permittivity, permeability and/or conductivity).
Antenna Measurements
Measurement of antennas from microwave to millimetre wave frequencies. In this area different types of antennas are investigated such as: antenna arrays, reflectarrays, lens antennas, leaky wave antennas, etc.
Frequency Selective Surfaces
Design, manufacture and characterization of Frequency Selective Surfaces (FSS).
Metasurfaces
Design, fabrication and measurement of metasurfaces capable of arbitrary wavefront manipulation, with a focus on achieving versatile, high performance planar antennas.
Millimetre wave band sensors
Sensors in the millimetre wave frequency bands have become relevant systems in many applications. The development of radars for advanced driving aids is one of the fastest growing applications. This technology has applications in many other fields such as industrial environments, the home or in biomedical applications.
Additive Manufacturing
Additive manufacturing is not a new concept, but today's incredible cost reductions have allowed it to penetrate industry and the home in ways that were unimaginable just a few years ago. The application of new technologies to the development of waveguide circuits or moulded antennas is the focus of research in our group. Projects are currently underway to develop circuit elements for 5G applications and millimetre wave sensors.
Wire-bonding
Wire bonding allows devices to be connected to chips without encapsulation using gold wires. Using this technology to connect circuits significantly reduces the effect of parasitic elements on response. The KS4223 is a soldering station that enables wedge connections. It can also be used to attack problems where back-to-back soldering is required.
Materials Printer
The printing of materials in ink formats allows the printing of circuits with conductive, dielectric and even semi-conductive inks. The FujiFilm Dimatix DMP2850 enables the printing of metallic inks based on silver nanoparticles and graphene flakes.
Chipless RFID
We research and develop RFID tags without a chip (Chipless RFID), an innovative technology that enables the identification and tracking of objects without the need for an integrated circuit. We focus on the design of resonant structures and the optimisation of the reading of these tags using electromagnetic waves.
Characterization of transmission media
We analyse the electromagnetic behaviour of different materials and structures to optimise signal propagation in waveguides, transmission lines and antennas. This allows us to improve the design of devices and systems in telecommunications, wireless sensors and high frequency circuits.
Microwave MEMS switches
MEMS (Microelectromechanical Systems) microwave switches are ideal for applications in telecommunications, radar and detection systems. In our laboratory, we design, manufacture and characterise them to improve their performance and reliability in advanced applications.
Switching matrixes
Are key devices in communications and radar systems, as they enable the efficient distribution of RF and microwave signals. In our laboratory, we work on the design and characterisation of advanced arrays that improve the performance of antenna networks, satellite communication systems and others.
PCB
Design and manufacture of integrated circuits for automotive, global wireless communications, microwave and millimetre antenna systems for 6G-based intelligent transport networks, and others.
