Thus, the need of instrument for the characterization is becoming unavoidable thing to be established. This paper reports the development of test-fixture in form of a parallel plate waveguide (PPW) to characterize the reflectivity and/or transmittivity of microwave device whereby the property of reflection and/or transmission can be achieved under normal incidence. Since the PPW is excited using a rectangular waveguide, a transition section which connects the rectangular waveguide and the PPW needs to be investigated to have an optimum performance required for microwave devices characterization. The tapering effect of transition section is examined and analyzed numerically in yielding the influences to the test-fixture performance. Here, a WR248 type rectangular waveguide which has working frequency of 2.60GHz to 3.95GHz for TE10 mode is used as coaxial-to-waveguide transducer for exciting the PPW. The result shows that the linear-tapered transition has better performance in term of bandwidth compared to the step-tapered one. In addition, the discussions of taper length and number of step-tapered transition related to the performance of test-fixture as well as the experimental characterization for linear-tapered transition are also presented.[/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]Coax-to-waveguide transducer,Linear-tapered transition section,Microwave devices,Parallel plate waveguide,Rectangular waveguide,Step-tapered transition section[/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.2014.6.1.12[/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]
