Abstract

This paper describes a hemi-elliptical dielectric lens antenna for Terahertz application. The design of antenna is done by integrating a hemi-elliptical dielectric lens antenna with a perforated substrate patch antenna to provide low loss, high directivity at low terahertz frequency. The initial geometry of the design is based on integral equations and ray optics which is optimized using Simulations (Ansys HFSS version 2016). The dielectric used for substrate is Rogers RT Duriod (Er=2.2) and for the lens we use Gallium Arsenide (Er=12.9) in this design. The central frequency of the designed antenna is 600GHz with a maximum directivity of 7dB and return loss of -30dB.
