Recently, there have arisen several new methods of aperiodic antenna array design that are capable of very low sidelobe level performance over ultra-wide bandwidths. The linear polyfractal arrays yielding acceptable performance over many octaves of bandwidth. Similarly, wideband planar arrays are created and optimized based on aperiodic tilings. In this paper, the raised-power-series (RPS) method...
Planar antenna arrays based on certain categories of aperiodic tilings have been shown to exhibit several useful properties, including a wide bandwidth void of grating lobes, relatively low sidelobe levels, and sparse element distributions. While these arrays possess beneficial properties, their performance is basically limited by the corresponding set of prototiles that make up the tiling, i.e. the...
