Comparison of the Peano–Gosper fractile array and the regular hexagonal array

A new class of modular broadband low‐sidelobe arrays, based on the theory of fractile (fractal tile) geometry, has been recently introduced. In this paper, the radiation properties of the Peano–Gosper fractile array are compared to those of the conventional square and hexagonal arrays. It is demonstrated that the Peano–Gosper array has the same desirable grating‐lobe conditions as the hexagonal array, while achieving a much lower overall sidelobe level.
