These reflections lead to a successful energy transmitted into the medium becomes smaller. This is indicated by a decline amplitude transmitted waves. To minimize this reflection is used as a medium of dielectric layer transition from the antenna to the medium. By using this dielectric layer from amplitude expected to signal that the medium will be higher. Apart from amplitude, should also noted ringing level. A good antenna has a small ringing level. Therefore, in this simulation is used resistive loading. With resistive loading is expected to wave reflection from the end of the antenna can be reduced. So with the imposition of resistive and dielectric layers are expected to signal that is transmitted to the medium has a low ringing level and also has a high amplitude.[/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]Dielectric layer,Field boundaries,Ground penetrating radar antennas,High amplitudes,Layered dielectrics,Resistive loading,Transmitted waves,Wave reflections[/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][/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][/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]
