Abstract

The paper reviews wideband radial-line slot array design and its suitability to develop wideband beam-steering antenna through near-field meta-steering (NFSM). A low-profile and highly efficient beam-steering antenna system can be realized using the wideband RLSA and pair of metasurfaces, which are placed in the near-field region of the RLSA. In NFMS systems, the base antenna remains fixed while the metasurfaces are rotated to steer the beam in both azimuth and elevation directions. The concept was first demonstrated with narrowband medium-gain antenna, and since then, it has been extended to design high-power systems, dual-band high throughout systems, and wideband steering systems.
