Design of Planar Goubau Line Antenna for Partial Discharge Measurement

This paper deals with design of planar Goubau line (PGB) antenna for partial discharge (PD) measurement. In the design, planar Goubau line antennas are simulated with a variety of shapes and sizes by using software HFSS to get the corresponding frequency response with the frequency of occurrence of PD. Planar goubau line antenna is designed with the type of substrate FR4_epoxy ranging from the size of the substrate with a length of 105 mm, width 60 mm, thickness 1.6 mm up to the size of the substrate with a length of 70 mm, width 40 mm, thickness of 1.6 mm. In the final results, antenna design that suitable for PD measurement is obtained with bandwidth, return loss (RL), VSWR as antenna parameters.
