为了减少工作在28 GHz和39 GHz频率的两个紧密间隔的微带贴片天线之间的互耦合，通过利用椭圆形超颖表面应用电磁隐身的概念。在本文中，我们表明，通过用专门设计的超颖表面斗篷包裹天线，不仅相互电磁相互作用显着减少，而且观察到辐射模式的恢复，就好像天线彼此完全隔离一样。解耦效应可以在相互S参数的减少中看到。这使得天线能够独立地辐射，即使它们被放置在非常接近的位置。
In order to curtail mutual coupling between two closely spaced microstrip monopole antennas operating at frequencies 28 GHz and 39 GHz, the concept of electromagnetic cloaking is applied by utilizing elliptical metasurfaces. In this paper, we show that by enveloping the monopole antennas with the specifically engineered metasurface cloaks, not only is there a significant reduction in the mutual electromagnetic interaction but also restoration in the radiation patterns are observed, as if the antennas were completely isolated from each other. The decoupling effect is seen in the reduction of mutual S-parameters. This enables the antennas to radiate independently even though they are placed in a very close proximity.
