Abstract / Description

A feasibility study is presented on the performance parameters of a novel on-chip antenna based on metasurface technology at terahertz band. Metasurface on-chip antenna is constructed on an electrically thin high-permittivity GaAs layer. Metasurface is created by engraving tapered slots on 11×11 array of circular patches fabricated on the top GaAs layer with metallic via holes that connecting the circular patches to the open-ended feeding slot-lines underneath of the structure. The antenna is coupled electromagnetic to the feed-line. The feed mechanism employed results in wideband performance across 410 GHz to 470 GHz. Radiation performance of the antenna are shown to significantly improve with the metasurface, in particular, the gain increases to 11.9 dBi and radiation efficiency goes up to 81.95%. Dimensions of the antenna are 8.6×8.6×0.053 mm3.
