title = "1-bit Wideband Fully-metallic Reflectarray Antenna",
abstract = "A 1-bit metal element is presented for wideband reflectarray design. Phase shift is achieved by alternating the height of the element. Comparing with the conventional one-stage metal block, the proposed two-stage metal block can provide wideband performance. The phase difference is within 180±10° in the band of 28.6 to 39.5 GHz. The reflection loss is very low, since no substrate is used. A reflectarray with 20 × 20 elements is designed. The simulated realized gain and aperture efficiency at 32 GHz are 23.03 dBi and 21.91 %, respectively. The aperture efficiencies of the 1-bit reflectarray antenna in the desired band are larger than 18%.",
