Abstract
A quasi-optical beam former includes a set of beam ports, a set of network ports, a quasi-optical device and at least one parallel-plate waveguide extending between the beam ports and the network ports, the beam ports and/or the network ports being superposed in at least two stages, each of the at least two stages being separated by a conductive plane common to two adjacent stages, the quasi-optical beam former comprising a resistive film placed in the continuity of the conductive plane.
