Antenna arrays formed of spiral sub-array lattices |
摘要 |
A antenna array (20) includes a plurality of periodic or aperiodic arranged sub-arrays (22). Each sub-array (22) includes a plurality of antenna elements (32) arranged in the form of a spiral (30). The sub-arrays (22) can comprise various spiral shapes to provide the required physical configuration and operational parameters to the antenna array (20). The elements (32) of each sub-array (22) are arranged to minimize the number of such elements (32) that intersect imaginary planes perpendicular to the spiral and passing through the spiral center. Such an orientation of the elements (32) minimizes grating lobes in the antenna pattern.
