CIMITEC is a research and technology transfer centre at the Universitat Autònoma de Barcelona dedicated to achieve innovative and customized solutions for communication systems. Constituted by doctors, engineers and technicians with a high degree of specialization, CIMITEC applies
Metamaterial-based technology in the following fields:
ADVANCED COMMUNICACION COMPONENTS
Customized filters, couplers, power dividers, and other RF/microwave components. Compact dimensions, high performance and multi-band, for application in technologies such as UWB, WiFi or RADAR.
We are also working in the development of algorithms based on Space Mapping techniques for their application in automated synthesis of components. The design of transmission lines based on artificial metamaterials requires a certain time in order to obtain the desired characteristics in each case, due to the large number of controllable parameters. The synthesis of these elements by using techniques such as Space Mapping reduces the design time and allows getting more efficient components.
RADIOFREQUENCY IDENTIFICATION SYSTEMS (RFID): NEW TAGS AND ANTENNAS FOR READERS
CIMITEC develops miniaturized and multiband antennas for RFID applications In UHF and microwave bands, and works on the development of tags able to operate with good performance on adverse environments, such as metal objects
CIMITEC devoloped a field-confinement device for its application as near-field antenna for RFID applications This device makes possible the implementation of UHF-RFID points-of-sale in retail shops , allowing only the detection of tags inside the coverage region, avoiding "false readings". Therefore, UHF-RFID tags could replace barcodes, improving logistic and payment processes in retail.
This technology can be used in other applications, such as stock control or access control, among others.
A flexible measurement system is avalaible in our laboratories for tag and antenna characterization.
NEW MICROWAVE SENSORS BASED ON METAMATERIAL STRUCTURES
Metamaterial-based structures can be applied in sensor devices. CIMITEC is currently developing structures for position, rotation and velocity sensors based on la modifying the symmetry of such structures
This kind of sensors is very interesting for space applications. CIMITEC develops in collaboration with the research group iTEAM (Universitat Politècnica de València) and the company EMXYS an angular velocity sensor for satellite positioning.
