Propagation tests were carried out on the horizontal and vertical polarization characteristics in a frequency range from VHF to X-band (150 MHz to 4.7 GHz). Field strengths along the road and field distributions in the cross section were measured. The attenuation constants in a straight-road section were obtained by the least-squares method using measured data. It is shown that the attenuation constants are experimentally minimum in a frequency range of 1-3 GHz for each polarization, and that field strengths in the cross section are close to cosine distribution in the horizontal direction, and in the vertical direction increase nearly monotonically with increasing elevation","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"19","nameIdentifierScheme":"WEKO"}],"names":[{"name":"山口, 芳雄"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEEE"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1109/15.2399","subitem_relation_type_select":"DOI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©(1988) IEEE.
