Low-Profile Multibeam Antenna Based on Modulated Metasurface
IEEE Transactions on Antennas and Propagation, 2023Linearly polarized (LP) multiport multibeam antennas (MBAs) based on modulated metasurface (MTS) are presented in this article. A key challenge for MTS to generate multiple independent beams is the mutual interference of different impedance modulations ...
