Title:
SPATIAL FILTERING SURFACE OPERATIVE WITH ANTENNA APERTURE FOR MODIFYING APERTURE ELECTRIC FIELD
Document Type and Number:
WIPO Patent Application WO2004008576
Kind Code:
B1
Abstract:
A spatial filtering surface (100) includes a dielectric substrate (106) and a plurality of spaced, geometrically configured, resonant elements (104) positioned on the dielectric substrate (106). The resonant elements (104) form concentric rings that each attenuate any electromagnetic radiation passing therethrough a different amount wherein a spatial filter transform is imparted for tapering the magnitude and phase of a produced aperture field.
