The antenna has been designed for transmission of monocycle pulses with duration of 5 ns (200 MHz central frequency) suitable for lowresolution GPR applications. The dipole is rolled to considerably reduce its length and resistive loading with the Wu-King profile is applied for suppression of late-time ringing, important for GPR. It is shown theoretically that the antenna radiates the pulse with no late-time ringing. Furthermore, by rolling the wires the antenna length is reduced by a factor of 4 with no evident negative impact on the antenna’s characteristics. A shield for the antenna has been designed, constructed and integrated with the antenna. Furthermore, it has been found that a tapered bow tie can be combined with the antenna in such a way that a significant increase in the antenna efficiency is obtained, resulting in a unique hybrid of a dipole and a bow-tie antenna. © 2007 IEEE.[/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 efficiency,Antenna length,Bow ties,Bow-tie antennas,Central frequency,Dipole antenna,Experimental analysis,GPR antenna,GPR applications,Ground-penetrating radar,International conferences,Low-resolution,Monocycle pulses,Negative impacts,Resistive loading,Transient antenna,Ultra wide bands,UWB antenna[/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]Dipole antenna,GPR antenna,Transient antenna,UWB antenna[/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/ICUWB.2007.4380958[/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]
