Maximally Sparse Near-field Shaped Focusing Arrays by Sequential Convex Optimization
The design of sparse arrays with a minimum number of elements is an emerging field of study as it can reduce the cost and complexity of near-field antenna arrays. A sequential convex optimization based method is proposed to obtain the op- timal array locations and excitations. A numerical example is presented to show the effectiveness of the proposed method, where the synthesized layout consisted of only 41 elements can achieved the same 3dB beamwidth and peak sidelobe level radi- ated by a uniformly spaced array consisted of121 elements.
