A radar antenna device (16) having an antenna arrangement (19) that is accommodated in a housing (17) and is provided with a protective plate (20) for being separated with respect to a furnace atmosphere formed within a furnace chamber, said protective plate (20) being disposed on the housing, a radar-transparent limp material layer (21) comprising pores being disposed as a shield at a distance upstream of the protective plate (20) in such a manner that a space which is separated by the material layer (21) with respect to the furnace chamber is formed, a fluid line opening into said space for applying a fluid flow to the material layer (21).
A radar antenna device (16) having an antenna arrangement (19) that is accommodated in a housing (17) and is provided with a protective plate (20) for being separated with respect to a furnace atmosphere formed within a furnace chamber, said protective plate (20) being disposed on the housing, characterized in that a radar-transparent limp material layer (21) comprising pores (30) is disposed as a shield at a distance upstream of the protective plate (20) in such a manner that a space (23) which is separated by the material layer (21) is formed with respect to the furnace chamber, a fluid line (24) opening into said space (23) for applying a fluid flow (26) to the material layer (21), wherein the radar-transparent material layer (21) has a fabric structure (33).
A method for shielding a radar antenna device (16) which emits radar radiation and comprises an antenna arrangement (19) disposed in a housing (17), said antenna arrangement (19) being provided with a protective plate (20) for being separated with respect to a furnace atmosphere formed within a furnace chamber and said protective plate being disposed on the housing, characterized in that a radar-transparent limp material layer (21) comprising pores (30) is disposed upstream of the protective plate (20) for shielding from the furnace atmosphere, in such a manner that a space (23) is formed between the protective plate (20) and the material layer (21), said space (23) being separated from the furnace chamber, and that a fluid flow (26) which interfuses the pores (30) of the material layer is applied to the material layer (21) via a fluid line (24) which conducts to the space (23) for generating vibrations in the material layer (21), wherein the radar-transparent limp material layer (21) has a fabric structure (33).
