In the numerical analysis, the electromagnetic simulator WIPL-D based on the method of moment is used. At first, the distance between the two elements is fixed to be a quarter wavelengths at the design frequency of 2.45 GHz. The front-to-back ratio is calculated. Then, by adjusting the length of the two elements and the distance between the two elements, a front-to-back ratio of 15.3 dB is obtained. The relation between the front-to-back ratio of this antenna and the feed point currents is discussed. The measured input impedance with 90 degree hybrid phase shifter agrees with the calculated result.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"ACES journal, 22(1), pp. 112-116; 2007","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Applied Computational Electromagnetics Society"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2007 ACES"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10848752","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"10544887","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Taguchi, Mitsuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Era, Kotaro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Kazumasa"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"200703JACES.pdf","filesize":[{"value":"278.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"200703JACES.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/17666/files/200703JACES.pdf"},"version_id":"0e6d91d5-15d5-4b5c-8932-b7d8cf8fee70"}]},"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":"Two element phased array dipole antenna","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Two element phased array dipole antenna"}]},"item_type_id":"2","owner":"2","path":["65"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-10"},"publish_date":"2009-04-10","publish_status":"0","recid":"17666","relation_version_is_last":true,"title":["Two element phased array dipole antenna"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:28:18.421371+00:00"}
