  • Self protected and transportable flat lattice antenna
    Patent number: 4899166
    Abstract: A flat, self protected and transportable lattice is provided using a radiating structure formed of a three-plate line, with sources forming a lattice etched on one of the conducting planes. This structure further comprises two identical foam sheets bonded by an adhesive which allows sliding in the two conducting planes of the radiating structure, each foam sheet being covered with a thin rigid bonded plate. The plates thus bonded are chosen transparent to the radiation and form a symmetrical structure whose inherent flatness and rigidity are ensured, which is self protected and which is also sealed by means of a banding system.
