Abstract
A sparse phased array including a generally logarithmic spiral lattice of multiple radiating and receiving elements defining a logarithmic spiral of no translational periodicity which ameliorates grating lobes, even for wide element placement. The array has a substantially equal unit cell size per radiating element which in turn best matches the array to the medium and is capable of operating at relatively high power levels in one or more frequency bands. The unit cells include an area wherein each of said unit cells include an area of space around the respective antenna element within which all points therein are closer to said respective antenna elements than to any other antenna element of said plurality of antenna elements.
