Gillard laurent.le-coq@univ-rennes1.fr INSTITUT D’ÉLECTRONIQUE ET DE TÉLÉCOMMUNICATIONS DE RENNES Introduction Antennas and Microwaves group Antenna test facilities Specific use and developments Conclusion 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 of 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
