The use of normal mode BHA is due to the ability of antenna to produce broadside radiation pattern with circular polarization required for wireless communication. The BHA is made of copper conductor wire with 2 numbers of its turns in which the pitch distance of each turn is 25.8mm yielding the antenna height of 51.6mm. The diameter of normal mode BHA is 8.68mm as of its circumference of 1/3λ. The antenna is fed by a 50Ω SubMiniature version A (SMA) connector through a microstrip balanced-unbalanced (balun) circuit which also acts as impedance matching circuit. The microstrip balun is deployed on a top side of FR4 epoxy dielectric substrate, while the bottom side is applied as its groundplane. The characterization result shows that the realized antenna could produce -10dB working bandwidth of 200MHz, gain of 5.12dBi, and a broadside radiation pattern workable at the center frequency of 3.3GHz. This can be an advantage to implement the antenna due to its compact size which can reduce cost of implementation.[/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]Balanced-unbalanced (balun),Bifilar helical antennas,Broadside radiations,Circularly polarized antennas,Design and implementations,Impedance matching circuits,Normal modes,Wireless communication applications[/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]Bifilar helical antenna (BHA),broadside radiation pattern,circularly polarized antenna,normal mode[/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]This work is partially supported by the Overseas Research Program, Institut Teknologi Bandung, FY2017 and the Postgraduate Team Research Program FY2017, the Ministry of Research, Technology and Higher Education, the Republic of Indonesia.[/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/TENCON.2017.8228362[/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]
