Abstract

A triangular metamaterial structure unit is presented and the effective permittivity and permeability parameters are retrieved from the transmission and reflection data. Simulation results show that the combined unit exhibits left-handed passband in terahertz (THz). Triangular electromagnetic metamaterial is applied to conventional THz and the characteristics of zero refractive index are used to produce horn antennas superstrate for directional radiation of electromagnetic, so as to improve the antenna directivity and gain. The experimental results show that antenna with triangular magnetic metamaterials results in weaken backward wave radiation, enhanced forward radiation efficiency enhancement and the directivity factor increased by 46.86 and the gain is increased by 2.77dB.
