laurent.le-coq@univ-rennes1.fr Design of radiating structures is a basis of main of our studies Antennas topologies specifications and are as wide as our topics and contract context :

small and miniature antenna
active and passive structure
array, reflect array, single element
printed technology, 3D structures
from 100MHz to 110GHz

Antenna measurements is a key step of the research process, but not used for certification purposes Characterization needs are not focus on having a very specific antenna test range but having a set

f test ranges that are easily adaptable to the specificity of each of our design

Mainly, our test ranges are :

used for measurement of low and middle gain antennas
used for measurement of narrow and ultra wide band antennas
easy to use to keep the characterization as a step of the design process
adaptable and reconfigurable if necessary

laurent.le-coq@univ-rennes1.fr Four facilities for radiation characterization Introduction Antennas and Microwaves group Antenna test facilities Conclusion Specific use and developments Measurements needs :

validation :

> classical design step > validation of software development > original topology of antenna and associated devices

reference values :

> simulation results > specific cut planes for software validation

not for certification

Context of investment :

financing thanks to contract, with supports of

CNRS, région Bretagne, Rennes Métropole, Université of Rennes 1, INSA Rennes

95% of utilization for our main needs
facility access depends on two main criteria :

> feasibility of measurement > acceptable with our current studies
