N2 - This study purposes a new design of a coplanar Vivaldi antenna using a Wave Slot structure that could be applied for radar applications. The Coplanar Vivaldi Antenna works in a frequency of 0.5 to 4.87 GHz. By adding a wave slot structure at the edge of the patch on both sides of the coplanar patch, it can increase the directivity of the antenna. We compare five types of Coplanar Vivaldi Antenna (CVA) with Wave Slot (WS) structures with different positions and tilt angles ie: Regular Coplanar Vivaldi Antenna (RCVA), Vertical Wave Slot Coplanar Vivaldi Antenna (VWS-CVA), Horizontal Wave Slot Coplanar Vivaldi Antenna (HWS-CVA), Left Tilt Wave Slot Coplanar Vivaldi Antenna (LTWS-CVA) and Right Tilt Wave Slot Coplanar Vivaldi Antenna (RTWS CVA). From the simulation results, an antenna with a wave structure can increase directivity. At frequency 2.5 GHz LTWS-CVA gets a directivity of 6,38 dBi while RTWS-CVA reaches a directivity of 8,44 dBi. At a frequency of 2 GHz, HWS-CVA yields an improvement of directivity as 4.92 dBi if it compares with RCVA, hence it could be applied for radar applications.
