Reduction of mutual coupling in antenna technology using elliptically shaped metasurfaces
by Moreno, Gabriel, M.S., The University of Mississippi, 2016, 112; 10160562
Abstract (Summary)

This thesis is devoted to the use of metasurfaces for the goals of the reduction of mutual coupling between closely spaced antennas and the increase of antenna bandwidth. This is done first using a graphene monolayer as a cloak to decrease mutual coupling and restore radiation patterns for closely spaced antennas at THz frequencies. The introduction of the graphene monolayer was also extensively studied in regards to the effect on the radiation properties of the antennas.

The use of metasurfaces also has other applications, in particular with the bandwidth of antennas, where an anisotropic metasurface can be used to drastically increase the bandwidth of wire monopole antennas over a ground plane. This was then moved to an elliptical structure, using a strip monopole antenna. The last structure explored was for a microstrip antenna, where the strip monopole antenna is now placed above a ground plane on a substrate.
