We design a planar\nYagi–Uda antenna to reduce transmission losses in communication with\nPVC pipe walls as propagation paths. Coupling efficiency between the an-\ntenna and a PVC pipe is improved by attaching a PVC adapter with the same\ncurvature as the PVC pipe’s inner wall to the Yagi–Uda antenna to eliminate\nany gap between the antenna and the inner wall of the PVC pipe. The use\nof a planar Yagi–Uda antenna with a PVC adaptor decreases the transmis-\nsion loss of a 5-GHz-band microwave signal propagating along a 1-m-lomg\nstraight PVC pipe wall by 7 dB compared to a dipole antenna. The channel\ncapacity of a 2 × 2 MIMO system using planar Yagi–Uda antennas is more\nthan twice that of the system using dipole antennas.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_language":"en","subitem_link_text":"https://doi.org/10.1587/transcom.2023EBP3061","subitem_link_url":"https://doi.org/10.1587/transcom.2023EBP3061"}]},"item_79_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEICE","subitem_publisher_language":"en"}]},"item_79_relation_18":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1587/transcom.2023EBP3061","subitem_relation_type_select":"DOI"}}]},"item_79_rights_19":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©IEICE","subitem_rights_language":"en"}]},"item_79_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8516","subitem_source_identifier_type":"PISSN"}]},"item_79_version_type_21":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"HIRATA Akihiko","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}]},{"creatorNames":[{"creatorName":"AKIYAMA Keisuke","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}]},{"creatorNames":[{"creatorName":"KABE Shunsuke","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}]},{"creatorNames":[{"creatorName":"MURATA Hiroshi","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}]},{"creatorAffiliations":[{"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"MIZUKAMI Masato","creatorNameLang":"en"},{"creatorName":"水上　雅人","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-07-03"}],"filename":"e107-b_1_197.pdf","filesize":[{"value":"5.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/2000224/files/e107-b_1_197.pdf"},"version_id":"527be1b1-8c86-4d16-b2eb-2e97ffcc026e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Yagi–Uda antenna","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microwave propagation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MIMO","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pipelines","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Improvement of Channel Capacity of MIMO Communication Using Yagi-Uda Planar Antennas with a Propagation Path through a PVC Pipe Wall","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Improvement of Channel Capacity of MIMO Communication Using Yagi-Uda Planar Antennas with a Propagation Path through a PVC Pipe Wall","subitem_title_language":"en"}]},"item_type_id":"79","owner":"20","path":["46","429"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-07-03"},"publish_date":"2024-07-03","publish_status":"0","recid":"2000224","relation_version_is_last":true,"title":["Improvement of Channel Capacity of MIMO Communication Using Yagi-Uda Planar Antennas with a Propagation Path through a PVC Pipe Wall"],"weko_creator_id":"20","weko_shared_id":-1},"updated":"2024-07-03T05:53:09.259250+00:00"}
