“…High decoupling and inter-element isolation of antennas have been achieved by utilizing defected ground structure (DGS) [1][2][3], parasitic elements [4][5][6], electromagnetic band-gap structures [7], polarization conversion isolators [8][9][10], and metamaterial-based DGSs [11,12]. These techniques, however, have limitations such as big size, multilayer structure, and high manufacturing complexity and cost.…”

In this paper, the method of mantle cloaking is utilized to decouple/isolate two densely interleaved patch array antennas operating at the same frequency but with orthogonal polarizations. To reduce the mutual coupling between the adjacent elements, vertical strips, as a type of elliptical mantle cloaks, are located at close proximity to the patches. At the operating frequency of f0 = 3.7 GHz, the edge-to-edge spacing of the elements of the two interleaved arrays is less than λ0/80 (1 mm) and the center–to-center spacing of each array elements is 0.7 λ0 (57 mm). The proposed design is implemented using 3D printing technology, and its performance in terms of return loss, efficiency, gain, radiation patterns, and isolation is measured for evaluation. The results show the radiation characteristics of the arrays are perfectly retrieved after cloaking similar to the isolated arrays. Decoupling of tightly spaced patch antenna arrays on a single substrate paves the way to achieve miniaturized communication systems with full duplex operation or dual polarization communication.
