Design of 77 GHz Vivaldi antenna for millimeter wave communication

The antenna was fed by a unilateral fin line and then transmitted to its taper slotline radiator. The design and fabrication of the substrate containing the fin line transmission section and tapered slot radiating section were carried out. The waveguides were also designed to house the fin line section of the substrate. Simulations were carried out using XFDTD software to determine the radiating characteristic of the antenna. A set of S-parameter and polarization curves of the designed 77 GHz antenna were shown.
