Optimization of Surface Impedance for Reducing Surface Waves between Antennas
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
Electromagnetic coupling between two aperture antennas in the shape of the open ends of parallel-plate waveguideslocated on the same metal surface has been analyzed. The design optimization of the surface impedance model isused to solve this problem. The required level of antenna decoupling is obtained taking into account the initial metal surface,which is a natural decoupling structure. The search method is applied to determine a minimum value of the antennacouplingcoefficient. The method of moments (MoM) technique has been used to solve the integral equations. Numerical solutionsfor optimized surface impedance distributions and antenna decouplings are presented.
