CELLULAR REFLECTING SURFACE OF ANTENNA Russian patent published in 2000 - IPC

FIELD: manufacture of antenna reflecting surfaces. SUBSTANCE: cellular structure of metal threads difficult to unknit in case of local damage is made in the form of rhomboid-cell surface of warp-knitted filet weave. Knitted in opposite sides of all cells formed by combination of opposing-lay double- hackle weaves along lay repeat are additional threads arranged so that difficult-to-unknit knot is formed at points where they change their direction in vicinity of cell ties. Cellular reflecting surface is manufactured from inflexible metal threads on warp-knitting Raschel machine using three hackles. EFFECT: improved stability of shape and resistance to local damage; adequate conformity to specified radar characteristics. 1 dwg
