“…2, the only thing which still remains to be fixed is the density of the tiling. In fact, opposite to the methods in [6] and in [18], which lead to a random partition of the plane, the present partition, summarized by means of Fig. 1, leads to a deterministic partition of the plane.…”

“…: sparse arrays [4,5,[8][9][10][11][12] (i.e., arrays whose uniformly excited elements are properly located onto a non regular grid), thinned arrays [13][14][15][16][17] (wherein, starting from an otherwise regular arrays, the required performances are achieved by properly withdrawing a certain number of elements), and clustered arrays [1,6,7,[18][19][20] (wherein the overall array is subdivided into a number of possibly different uniformly excited sub-arrays). By noting that a number of hybrid solutions [21][22][23] are also possible, we will focus our attention on the third chance.…”

“…Also, in order to have directivity patterns as large as possible, a good aperture efficiency has to be realized (i.e., one should not have significant holes throughout the aperture). These two requirements are fulfilled by the solutions proposed in [6,18], wherein the so called domino and polyomino array antennas have been introduced.…”

Abstract-This paper presents an innovative Direct Radiating Array (DRA) architecture exploiting aperiodic tilings of the plane. In particular, a pinwheel tiling has been selected in order to fix positions of the different radiating sources, which are constituted by properly shaped elements. Such a choice allows to achieve a good aperture efficiency and very low pseudo-grating lobes while using only two different kinds of radiating elements. Preliminary results are shown and discussed with reference to both cases wherein the single tiles are not fully populated and wherein ad-hoc sub-array radiators are used. The very encouraging results achieved leave open the way for further interesting possibilities.

“…Thus the better subarray pattern, such as the 'flat-topped pattern', can be approximately obtained [15,16]. The rationale of interlaced or overlapped subarrays have been understood for years and already demonstrated in practice [17]. Recently, the mathematics theory of the design of overlapped subarray is presented in [18] in a signal-processing viewpoint.…”

“…Recently, the mathematics theory of the design of overlapped subarray is presented in [18] in a signal-processing viewpoint. However, the interlaced or overlapped subarrays are relatively difficult and costly to build [6,17,19]. The irregular-shaped subarray partitioning is relatively easily realised and has been studied for many years [1,20,21].…”

Beamforming properties and design of the phased arrays in terms of irregular subarrays

Large phased arrays are often organised by subarrays given the current state of technology. The irregular subarray architecture, which can effectively mitigate the quantisation lobes, has received a renewed interest in recent years. Recent researches present some innovative particular irregular subarrays to provide practical means to eliminate the quantisation lobes using several (even only one) kinds of subarray. However, there is no single, neat theory of the irregularly partitioned array antennas in the literature. This study presents some derivations of the beamforming properties for arrays with arbitrary subarray partition to fill this gap. Derivations have led us to introduce a novel approach to assess the radiation properties which is useful for the systematic design of phased arrays. Numerical experiments are carried out to validate the authors' derivations. Additionally, an elaborate example illustrates a design discipline for a limited-field-of-view array with polyominoshaped subarrays.
