Reactive terminations are connected to the parasitic elements, and the reactance values are determined to achieve stochastically high channel capacity for the environment targeted. This method treats the S-parameter and propagation channel of the antenna, including the parasitic elements, as a combined circuit. The idea of the \u0027parasitic channel,\u0027 which is observed at the parasitic antenna, is introduced to simplify the optimization procedure. This method can significantly reduce the number of necessary measurements of the channel for designing the antenna. As a design example, a bidirectional Yagi-Uda array, which has two driven antennas at both ends of the linear array, is measured in an indoor environment. The resulting design offers enhanced channel capacity mainly due to its improved signal-to-noise ratio compared to the antenna without the parasitic antennas.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1587/transcom.E93.B.2578", "subitem_relation_type_select": "DOI"}}]}, "item_5_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://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright(C)2010 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_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10826261", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168516", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Honma, Naoki"}], "nameIdentifiers": [{"nameIdentifier": "5585", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishimori, Kentaro"}], "nameIdentifiers": [{"nameIdentifier": "5586", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kudo, Riichi"}], "nameIdentifiers": [{"nameIdentifier": "5587", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takatori, Yasushi"}], "nameIdentifiers": [{"nameIdentifier": "5588", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiraguri, Takefumi"}], "nameIdentifiers": [{"nameIdentifier": "5589", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mizoguchi, Masato"}], "nameIdentifiers": [{"nameIdentifier": "5590", "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": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "E93-B_10_2578-2585.pdf", "filesize": [{"value": "2.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2000000.0, "url": {"label": "E93-B_10_2578-2585.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1787/files/E93-B_10_2578-2585.pdf"}, "version_id": "e9fd7585-6539-4c4b-ae3f-4974affa7735"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "MIMO", "subitem_subject_scheme": "Other"}, {"subitem_subject": "parasitic antenna", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mobile antennas", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Yagi-Uda arrays", "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": "A Stochastic Approach to Design MIMO Antenna with Parasitic Elements Based on Propagation Characteristics", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A Stochastic Approach to Design MIMO Antenna with Parasitic Elements Based on Propagation Characteristics"}, {"subitem_title": "A Stochastic Approach to Design MIMO Antenna with Parasitic Elements Based on Propagation Characteristics", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/30681", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-02"}, "publish_date": "2014-12-02", "publish_status": "0", "recid": "1787", "relation": {}, "relation_version_is_last": true, "title": ["A Stochastic Approach to Design MIMO Antenna with Parasitic Elements Based on Propagation Characteristics"], "weko_shared_id": null}
