In this paper, a theoretical method which allows to compare antenna diversity systems is described. A new metric, the ldquoreferenced diversity gainrdquo is also introduced. A new small UWB (ultra wide band) antenna (France Telecom R&D patent) is used in a dual-antenna system which is compared with another system using an UWB antenna designed by the LCIS/INPG laboratory.
This proposed methodology is an interesting tool which allows to compare several multi-antennas systems designed for a given application. This comparison is made possible thanks to the introduction of the referenced diversity gain. This methodology has the advantage to take into account a group of pondered situations which describes a real application. It is now possible for manufacturers to choose...
