It is required to monitor the isolation conditions on power apparatus. The isolation system allows an important role in the operating system on power apparatus. Some sensors have been designed or developed to detect PD phenomenon in power apparatus isolation based on the working principle of each sensor. One of them is an antenna. In this research there are three new designs of bowtie antennas. Two of them are double layer bowtie antennas and one single layer bowtie antenna. The design of the three bowtie antennas is double layer bowtie antenna with edge modification, double layer bowtie antenna with middle sliced modification and single layer bowtie antenna with edge modification. The antenna has designed with FR4-epoxy substrate which has dimensions of length and width of substrate is 160mm and 54 mm, thickness is 1.6 mm. Antennas are designed in the frequency range of 300 MHz – 3 GHz. 3D-HFSS software is used to design antennas. The antenna that has been designed is then implemented on printed circuit board (PCB) material and measured using a vector network analyzer (VNA) to determine the antenna parameter characteristics. Antenna characteristic parameters which include return loss (RL), bandwidth and VSWR show the corresponding results based on the simulation results and measurement results. The three antenna designs have RL values L -10dB and VSWR ≤ 2. Testing of bowtie antennas for detecting PD in air isolation using plate needle electrodes. PD test results show the design of the double layer bowtie antenna with edge modification radius 25 mm and double layer bowtie antenna double layer with middle sliced modification of scale 0.5 has good sensitivity in detecting PD compared to single layer bowtie antenna with edge modification radius 25 mm. In addition, the double layer bowtie antenna with edge modification radius 25 mm and bowtie antenna double layer with middle sliced of scale 0.5 has a wide bandwidth value when compared to a single layer bowtie antenna with edge modification radius 25 mm.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antenna characteristics,Antenna parameters,Bow-tie antennas,Needle electrodes,Printed circuit boards (PCB),Return loss,Vector network analyzers,VSWR[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]bandwidth,bow-tie antenna,partial discharge,return loss,UHF,VSWR[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICA.2019.8916704[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
