Raindrops cause attenuation of radio waves by both absorption and scatter. Absorption involves dissipation of some of the energy of an electromagnetic wave as heat. Scatter involves diversion of some of the energy of the wave into directions other than the forward direction. The theoretical performance of short pulse transmission over rain areas are then compared with experimental data which was performed in the campus environment. The bandwidth of the signal used in this experiment is 7.5 GHz and the measurement setup consists of Vector Network Analyzer, an UWB antenna array, metal sheet as reference reflector and raingauge. Our preliminary study, both numerical and experimental results concluded that the rain-filled medium modify the spectrum of UWB signals. This spectrum degradation will impact on pulse spreading of the transmitted monocycles in time domain and cause bit errors.[/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]Experimental investigations,Measurement setup,Rain gauges,Reference reflectors,Theoretical performance,Uwb antenna arrays,UWB signals,Vector network analyzers[/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]
