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.

Abstract: A multiband phased array antenna includes a substrate, and dipole element arrays extending outwardly from an imaginary center point on the substrate. Each dipole element array includes dipole antenna elements arranged in end-to-end relation and having a dipole size different than a dipole size of dipole antenna elements of at least one other dipole element array. A ground plane is adjacent the dipole element arrays, and a spacing between the dipole element arrays and the ground plane is different between the dipole element arrays having different size dipole antenna elements. The ground plane has a plateau shape for providing the different spacing between the dipole element arrays.

A ground plane is adjacent the dipole element arrays and has a different spacing therefrom in an outward direction from the imaginary center point. The different spacing between the ground plane and the dipole element arrays increases from the imaginary center point towards an edge of the substrate.
