Patent ID: 6879291

Claim:
An antenna array comprising: a plurality of facets disposed around an axis, each of said plurality of facets having sides connectively abutting the sides of an adjacent facet, said plurality of facets forming a faceted tube; at least one patch antenna disposed on each of said plurality of facets; at least one radio frequency interface module disposed therein; a plurality of signal tracks disposed across said plurality of facets interconnecting said patch antennas across said connectively abutting sides to said radio frequency interface module; at least one ground plane, separated from said at least one patch antenna and said plurality of signal tracks by a dielectric having a thickness; and each facet having a substantially planar region thereunder said at least one patch antenna, and each facet having a first curved region under at least a portion of said plurality of signal tracks, wherein said first curved region has a radius of curvature great enough to avoid discontinuities in RF propagation along said signal tracks.
