Abstract :
Summary from only given. The dramatic influence of the substrate lens design on the achievable bandwidth in THz-time domain spectroscopy (TDS) system has not been generally appreciated. We have measured the angular emission pattern of radiation emitted from a bow-tie antenna coupled to each of the two lens designs. The measurements have been performed using a fiber-coupled THz receiver, mounted on a pivoting rail.
