A low radar cross section (RCS) Vivaldi antenna based on the polarization conversion metasurface (PCM) is presented in this paper. The PCM unit consists of two pairs of L-shape metal strips and an air ...

In this manuscript, we present a new antenna design applied to the THz band, based on using a Vivaldi construction and theory. Design of pass band is 155-180 GHz, Using three-dimensional (3D) ...
