Abstract
A phased array antenna consisting of like multi-element tiles whose elements are located so as to produce an irregular array when the tiles have mutually different orientations, e.g., random. The resulting irregular array reduces the effective translational period of the array elements, which in turn ameliorates grating lobes even for wide (one wavelength) effective element spacings. An antenna so designed can maintain low peak sidelobes at far higher frequencies than a conventional translational-periodic phased array antenna of the same element density.
