The authors have proposed and examined a technique of measuring arbitrary reflection coefficients using a hybrid coupler and a sliding short. It has a possibility of accurate measurement of the reflection coefficient whose magnitude is close to unity, because S parameters of the components used in the measurement system are measured In this paper, we apply it to the measurement of the radiation efficiency of the antenna based on the Wheeler method and show the valid ity of the proposed technique.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"International Symposium on Antennas and Propagation (ISAP 2011) : October 25 - 28, 2012 Lotte Hotel Jeju, Jej, Korea.","subitem_description_type":"Other"}]},"item_8_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Institute of Electronics, Information and Communication Engineers"}]},"item_8_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ap-s.ei.tuat.ac.jp/isapx/","subitem_relation_type_select":"URI"}}]},"item_8_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright(C)2011 IEICE"},{"subitem_rights":"本文データは学協会の許諾に基づきEJサイトから複製したものである"}]},"item_8_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kobayashi, Yohei"}],"nameIdentifiers":[{"nameIdentifier":"19","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishii, Nozomu"}],"nameIdentifiers":[{"nameIdentifier":"168883","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-26"}],"displaytype":"detail","filename":"2011_E10_1002.pdf","filesize":[{"value":"297.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2011_E10_1002.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/30913/files/2011_E10_1002.pdf"},"version_id":"60b70d19-8d68-4da2-8a1d-7fe5ed117084"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Hybrid coupler","subitem_subject_scheme":"Other"},{"subitem_subject":"Sliding short","subitem_subject_scheme":"Other"},{"subitem_subject":"Wheeler method","subitem_subject_scheme":"Other"},{"subitem_subject":"Small antenna","subitem_subject_scheme":"Other"},{"subitem_subject":"Radiation efficiency","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Radiation Efficiency Measurement Based on Wheeler Method Using Hybrid Coupler and Sliding Short","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Radiation Efficiency Measurement Based on Wheeler Method Using Hybrid Coupler and Sliding Short"}]},"item_type_id":"8","owner":"1","path":["457","1822"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-11-12"},"publish_date":"2014-11-12","publish_status":"0","recid":"30913","relation_version_is_last":true,"title":["Radiation Efficiency Measurement Based on Wheeler Method Using Hybrid Coupler and Sliding Short"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T04:01:25.534571+00:00"}
