Electronic Beam-steering Using 1-Bit Digital Rflective Metasurface at Ka Band
This paper presents a 1-bit digital reflective metasurface operating at 35 GHz. A simple 1-bit digital element structure employing one PIN diode, which has a fractional bandwidth of 5.4%, is proposed. Based on the element, a 20 × 20 metasurface is constructed. By properly leveraging ON and OFF states of PIN diodes mounted on metasurface, two-dimensional electronic beam-steering can be realized to tailor the incoming waves fed by a horn antenna. Finally, high-gain beam-scanning, orbital angular momentum vortex beams, and near-field focal beams are theoretically achieved by using aperture field approach.
