Design of a filtering antenna : Application to the electromagnetic horn

The need to increase the capacity of the terminals of communication led us to imagine the design of multifunction devices. This is in particular interesting for the elements of the transceiver which are not a priori integrable in a monolithic way, such as the antenna and the input filter. It is possible to design an antenna which integrates the function of filtering, this being possible in various technologies. In this paper, in order to update the problems involved in the design, we propose the study of an electromagnetic horn in which a function of filtering is directly integrated.
