| Popis: | Two tightly spaced, interleaved microstrip monopole antenna arrays operating at microwave frequencies are decoupled by employing mantle cloaking method. We use elliptical metasurfaces specifically tailored for the cross-coupled elements of the distinct arrays and show that by wrapping each antenna element with the metasurface cloak, the undesired cross-coupling between the elements at frequencies 28 GHz and 39 GHz is eliminated, restoring their radiation patterns as if the arrays were isolated from each other. In this paper, the cloaking and decoupling effect is scrutinized and evaluated to improve the functionality of the coupled arrays in terms of their radiation patterns and realized gain, when all the antenna elements are excited simultaneously. Consequently, the monopole antenna arrays, even though placed in close proximity, can radiate independently for a wide range of beam scanning angles. |
