The antenna configuration named as cavity-backed UWB printed monopole antenna is similar to a waveguide transducer in which the probe used for the excitation is replaced with a UWB printed monopole antenna. The used cavity has the cross-section size of 110mm × 100mm with the depth of 75mm. Meanwhile the antenna which is used for performance enhancement is a UWB printed monopole antenna made of a 1.6mm thick FR4 epoxy dielectric substrate with the size of 72.8mm × 60mm. Some of its parameters such as reflection coefficient, gain, and radiation pattern are used as the performance indicators. After fabrication process, the experimentation is carried out by measuring characteristics of realized antenna configuration. It is found that the use of cavity could change the radiation pattern from omnidirectional to unidirectional and enhance the gain up to 6.6dBi at a certain working frequency.[/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 configurations,Cavity,Dielectric substrates,gain,Ground Penetrating Radar,Performance enhancements,Performance indicators,Printed monopole antennas[/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]Cavity,enhancement,gain,printed monopole antenna,radiation pattern,ultra-wide band (UWB)[/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 postgraduate team research program (Penelitian Tim Pasca Sarjana) FY2017 and the research incentive program of national innovation system (Insentif Riset SINas) FY2017 from the Ministry of Research, Technology and Higher Education, 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/APMC.2017.8251513[/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]
