Abstract (en)
[origin: US4878060A] 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.
