Patent ID: 7084822

Claim:
A traveling wave radiating aperture, comprising: a substantially vertical support structure; a conducting interior structure within the support structure, having a first and second end; a plurality of vertically arranged pairs of radiating elements, circumferentially connected to the support structure; and radiating elements-to-interior structure couplers, capable of transferring a digital energy signal input from the first end of the interior structure to pairs of the vertically arranged radiating elements and capable of transferring an analog energy signal input from the second end of the interior structure to pairs of the vertically arranged radiating elements, wherein the pairs of radiating elements are of substantially opposite orientation with respect to each other and on substantially opposing sides of the support structure, each pair of radiating elements being azimuthally shifted 90° from a neighboring pair of radiating elements and positioned approximately a distance of one quarter wavelength of a nominal frequency from the neighboring pair of radiating elements.
