Design and fabrication of vivaldi antenna as partial discharge sensor

This study discusses the design and fabrication of vivaldi antennas as partial discharge (PD) sensors for oil insulation media. In design, the vivaldi antenna is designed using HFSS software. Vivaldi antenna is designed with FR4_epoxy substrate type with with 20.02 cm of length, 15 cm of width, and 1.6 mm of thickness. After that the antenna is tested by using Vector Network Analyzer (VNA) to know the value of Return loss and VSWR and the antenna is tested again to measure the magnitude of the partial discharge signal.
