Decoupling Patch Antenna Array Using Magnetic Metamaterials

In this paper, we propose a thin magnetic metamaterial (TMM) for patch antenna decoupling. Due to the strong electromagnetic (EM) waves coupling in the dielectric substrate, a TMM with negative permeability in the working frequency band of patch antenna array embedded in the dielectric substrate is designed, which can block the propagation of EM waves in the dielectric substrate and realize the decoupling of the patch antenna array. This technique can effectively decouple the patch antenna array.
