All rights reserved.This paper deals with the development of printed log-periodic dipole array (LPDA) antenna in reduced size by applying fractal Koch geometry structure. The proposed printed LPDA fractal Koch antennas which are deployed on FR4 Epoxy dielectric substrates with the thickness of 1.6mm and relative permittivity of 4.3 are designed to have working bandwidth from 1.5GHz to 3GHz to cover some frequency bands of wireless communication. Some basic properties of antenna are analyzed numerically related to the physical parameters and its iterations in order to have optimum performance design. Three different iterations of printed LPDA fractal Koch antenna called as 0th, 1st, and 2nd iterations are introduced for the performance analysis. It shows that the printed LPDA fractal Koch antenna with the 2nd iteration has size reduction up to 21.18% and 25.28% than the 0th iteration and 1st iteration, respectively. Whilst from the performance result, although some properties of operating frequency and gain still need more improvement it shows that the 2nd iteration antenna has a better performance compared to others in term of working bandwidth.[/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][/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]Fractal koch geometry,Iteration,Log-periodic dipole array,Size reduction[/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/10.15676/ijeei.2015.7.2.5[/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]
