Abstract :
This paper describes our contribution in the RNRT project called LUTECE, dedicated to the emergency localisation of cellular phones. This contribution takes place in the field of antennas, with the development of two biband systems: a directive array for the emission part, and a circular array of five elements with separated outputs for the receiving part. Different evolutions of these antennas are presented starting from the same basic element, finally optimised on a dielectric substrate to offer good mechanical characteristics. All antennas are studied using our FDTD code.
