LEAT - UMR 6071
The
Electronics, Antennas and Telecommunications Laboratory
(LEAT) is a joint Research laboratory supported by CNRS and the
University of
Nice-Sophia Antipolis. The laboratory director is Christian Pichot du
Mézeray.
The total staff on September 1st 2010 is 79 including 36 permanent
positions (Full
Professors, CNRS Research Director, Associate & Assistant
Professors,
Engineers, Technicians, and Administrative Assistants) and 43
non-permanent
researchers (Ph.D students, post-docs, invited researchers, ...).

The Laboratory Facilities:
1. Technology Unit
Provides infrastructure and construction expertise for the realization of large printed antennas;
Provides expertise for antenna assessment – measuring return loss to 40 GHz.
2. Anechoic Chamber
The chamber dimensions are 8.70 m x 4.3 m x 4m for radiation pattern measurements from 820 MHz to 110 GHz;
There are 2 fully automated rotating systems spaced at a distance of 4.60 m – one for transmission and one for reception; The systems are coupled to a fully automated recording facility.
3. Near-Field Measurement System
The system has a bandwidth from .7 to 8 GHz and is used for characterizing circuits, antennas and other radiating devices such as RFID tags.
It is used for the E or H-Field or surface current mapping using an X-Y traveling system with accuracy of the order of 1 mm.
4. Probing Station for Microelectronic Components
The station is used for the analysis of microelectronic components, chips and circuits working from 50 MHz to 60 GHz, with automatic calibration; Measurements can be done on wafers up to 8 inches.
5. Special Equipment
Consists of a phase-noise meter working up to 20 GHz, with a case-to-case measurement option with external or internal VCO.
6. Computer Resources
Numerous workstations including Softwares for analysis, simulation and CAD (FP-EMMA-TLM, Zeland IE3D, Momentum, Ansoft HFSS, Ansoft Designer, ADS, SR3D);
Connections to large French Academic Computer Centers.
All these investigations are carried out through research contracts and collaboration agreement with private companies such as THALES, RADIALL, FRANCE TELECOM, Texas Instruments, Synopsys, Scaleochip, NXP, Mentor Graphics, ASK, RFMagic, InsightSiP, SENSeOR, and with research institutions, and academic laboratories including the French Public Works Research Laboratory (LCPC), ONERA (France), Institut d'Electronique, de Microélectronique et de Nanotechnologie (IEMN, France), Institut d'Electronique et des Télécommunications de Rennes (IETR, France), Institut de Recherche en Electrotechnique et Electronique de Nantes Atlantique (IREENA, France), XLIM (France), Institut Matériaux Microélectronique Nanosciences de Provence (IM2NP, France), Laboratoire des Sciences et Techniques de la Communication et de la Connaissance (Lab-STICC, ENSTB, Brest), FEMTO-ST (France), TELECOM Paris Tech, ENSTA (France), Laboratoire de Sondages Electromagnétiques de l'Environnement Terrestre (LSEET, France), Géosciences Azur (France), Laboratoire d'Energétique, d'Electronique et de Procédés (LE2P, Université de la Réunion), Queen's University of Belfast (UK), Delft University of Technology (Netherlands), Helsinki University of Technology (TKK, Finland), University of Florence (Italy), University of Trento (Italy), University of Ulm (Germany), University of California at Los Angeles (UCLA, USA), University of Hawaii at Manoa (USA), University of British Colombia (UBC, Canada), Lincoln University (New-Zealand), and the Electronic Navigation Research Institute (ENRI, Japan).
LEAT participates in various French or European organizations
such as the European School of Antennas (ESoA), COST "Antenna Systems & Sensors for Information Society Technologies" (ASSIST), the Regional Competitiveness Clusters (known as "pôles de compétitivité") "Secure Communicating Solutions (SCS)", "Risks", "Pegase", and "Sea PACA" to the Design Platform of the PACA region (Provence-Alpes-Côte d’Azur) of the Integrated Microelectronics Center (CIM PACA) for:
• Sharing State-of-the-Art Tools for the Design of SOCs of Communicating Objects;
• Facilitating and Supporting Cooperative Projects of Design Methodologies (SSCO, SYS2RTL, TYM);
• Offering Access of State-of-the-Art Design Tools to SMEs for Innovative R&D projects.
