N2 - Combining the advantages of the phase tunability provided by active frequency selective surfaces (FSSs) and the beam-steering scheme used in conventional 1-D Fresnel-zone-plate (FZP) antennas, we report in this communication a 2-D beam-steering FZP antenna that needs only 180° phase tunability. Compared with transmit arrays, while the substrate layers are reduced by a half, a phase compensation strategy is used to enhance antenna specifications. To verify the proposed approach, a radome implemented based on an active, reconfigurable FSS was designed, simulated, and experimentally implemented. With a simple three-layer structure, the implemented FZP antenna works within an ultrawide bandwidth ranging from 5 to 6.3 GHz, corresponding to a 21% relative bandwidth. With a gain up to 19.3 dBi, the scanning range reaches ±45° in both horizontal and vertical planes. This cost-effective, simple-structured antenna can be potentially used in diverse RF and microwave applications.
