Decoupling of Dipole Antenna Array on Patch Type Meta-Surface with C-Shaped Parasitic Element

A low-profile and decoupling dipole antenna array is achieved by combining a proposed C-Shaped parasitic element and a patch type meta-surface. Based on the moment method analysis results, it is clarified that our proposed parasitic element can suppress mutual coupling between the dipole antenna elements without undesired cross polarized radiation. In addition, the maximum decoupling effect of 15 dB is achieved.
