Abstract:

When steering or tilting the beam of a planar high-gain antenna using a near-field phase gradient metasurface, undesirable side lobes are often noted. These side lobes can be predicted reasonably well by exciting the metasurface with a normally incident uniform plane wave but direct optimisation of such an electrically large metasurface to reduce strongest undesirable side lobes is computationally very expensive. Here we have applied a more efficient approach to reduce the levels of all side lobes below-20 dB.
