Abstract

The invention proposes a transmitting/receiving device comprising at least one transition zone which comprises a means of transforming a polarized wave of a first polarization into an electrical signal; a second means of transforming an electrical signal into a polarized wave of the second polarization; and a first filtering zone placed between the antenna and the transition zone, the first filtering zone comprising a waveguide filter polarized in the second polarization direction, the said filter being transparent in the first polarization direction.
