Abstract:
1. An ultra-wideband antenna array architecture, comprising: a first array of radiating elements, wherein each first array radiating element has a first width; a second array of radiating elements, wherein each second array radiating element has a second width greater than said first width; and a third array of radiating elements, wherein each third array radiating element has a third width greater than said second width; and wherein said first, second, and third arrays are positioned in a wavelength-scaled lattice and have an ultra-wideband antenna configuration such that said first, second, and third arrays when powered up operate together as an integrated aperture that generates a substantially grating lobe-free beam over a continuous ultra-wideband range of frequencies; and wherein each said width is the lattice spacing of adjacent elements in each said array; and a feed means for feeding power to each array.
