The dual band power divider is designed and deployed on a 0.787 mm thick RT/Duroid® 5880 dielectric substrate. To reduce the overall size, a meander pattern is applied in the design process. The proposed power divider is characterized by use of a commercialized simulation software in dealing with the specifications required by a local oscillator system such as low insertion loss and good impedance matching. Based on the design result, the dual band power divider which takes the dimension of 55 mm × 42 mm is realized through wet etching technique. The measured insertion losses at the center frequencies of 2400 MHz and 4900 MHz are less than 1.6 dB. Meanwhile, the measured Voltage Standing Wave Ratio (VSWR) at the first center frequency of 2400 MHz is less than 1.5 at both input and output ports. However, at the second center frequency of 4900 MHz, the measured VSWR is 1.253 at the input port and 2.777 at the output port. The measured insertion loss and VSWR for the first frequency band have good agreements with the simulated ones, whereas for the second frequency band the measured VSWR at the output port shifted to the frequency of 4440 MHz.[/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 substrates,Dual Band,Local oscillator systems,Local oscillators,Meander line,Power divider,Simulation software,Wet etching techniques[/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]dual band,local oscillator,meander line,mi-crostrip,power divider[/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/TSSA48701.2019.8985464[/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]
