  • Microwave plane antenna with suspended substrate system of lines and method for manufacturing a component
    Patent number: 4878060
    Abstract: Multi-element microwave plane antenna formed from at least two metallic sheets (156, 157) on which separating studs (4, 19) are silk-screen printed and on which is inserted at least one block (50) of waveguides (2). The assembly of two such sheets forms a sandwich enclosing a printed circuit (195) carrying microwave lines which emerge into the waveguide.

  • Microwave plane antenna simultaneously receiving two polarizations
    Patent number: 4829314
    Abstract: Multi-element microwave plane antenna for receiving satellite television signals with two simultaneous polarizations. The antenna is provided with two systems of lines (1) whose ends (3, 30) form probes emerging into wave-guides (2). The probes of one system (3) are perpendicular to those of the other system (30). Between the two systems of lines there is placed only a thin sheet (150) bored with cross-shaped cut-outs (6), and provided with separating studs made from a silk-screen-printed insulating material.
