Abstract

In this paper, a 1-bit, high gain and wide-band reflectarray metasurface is proposed. The proposed reflectarray operates from 0.9 THz to 1.4 THz giving operational bandwidth of 0.5 THz. The realized gain achieved is 32 dB at 1.4 THz while the maximum simulated aperture efficiency is calculated to be 55%. The reflectarray is designed on polyimide substrate with permittivity of 3.48 and loss tangent of 0.03 at THz frequencies. The dimension of the metasurface is 3×3 mm2 and contains 3904 patch elements illuminated by a THz horn antenna. With high gain and flexible nature of the polyimide, the proposed metasurface is also suitable for wearable application.
