Transient UWB radiation with beamforming capacity : Multielement array design

This paper deals with the architectures which can be envisaged with regard to antenna arrays for UWB applications. Firstly, the advantage of a system fed by n generators, in opposition with a system fed by one generator, is presented. Then, the system which permits an easy beam steering is the subject of an optimization study concerning the delivering of high power radiations. A technique making the augmentation of the front to back ratio possible is also described.
