摘要：

An integrated terahertz (THz) H-plane horn antenna made of an electromagnetic crystals (EMXT) straight waveguide feed and a gradually flared horn is investigated. The EMXT structure is composed of metallised periodic square rods with dimensions of 48 x 48 x 241 mu m (width x length x height). The THz horn antenna is simulated using the finite element method and fabricated by microelectromechanical systems technology on silicon substrate. Measured attenuation loss of the EMXT straight waveguide is 0.17 dB per wavelength at 0.5 THz (lambda = 600 mu m). Good radiation patterns with 25 degrees half power beam width and a low sidelobe of -18.2 dB in the H-plane are demonstrated at 0.5 THz.
