Abstract
The invention concerns a reflector (8) of radio frequency (RF) energy. The reflector includes a first web layer (9a) formed from a knit of at least a first conductive filament (11a), and a second web layer (9b) formed of a knit of at least a second conductive filament (11b). The first and second web layers can be formed as an open mesh 10. The second web layer is positioned on the first web layer to form a stack. Fastening members (14, 16) are disposed at intervals across a surface of each of the first and second web layers. The fastening members are advantageously configured to secure the first web layer to the second web layer. The invention also concerns a reflector antenna formed using the reflector of radio frequency energy. The reflector antenna includes antenna support elements (18), and the first and second web layers are secured to the antenna support structure to define a curved three dimensional surface.
