dc.description.abstractIn this work, a procedure based on the Intersection Approach, is proposed to synthesize the near-field pattern of transmitarray antennas. First, the model for the computation of the amplitude and phase of the electric field in the near-field region is described and validated by comparison with full-wave simulations. Next, the proposed phase-only synthesis algorithm is detailed. Using fast Fourier transforms, it iteratively seeks for a feasible aperture phase profile that can fit near-field pattern constraints. The procedure is applied to synthesize a transmitarray generating a near-field shaped pattern on a plane parallel to the aperture. The impact of a uniform phase quantization on the near-field pattern and amplitude is analysed to provide design guidelines.
