The circular microstrip antenna is calculated using the cavity model. The electromagnetic fields within the antenna cavity are determined from the impedance boundary condition at the side aperture. The contribution from the region outside the antenna is taken into account by the wall admittance. The wall admittance is defined by the magnetic field produced by the equivalent, magnetic current at the aperture. The magnetic field is calculated by the spectral domain method. The wall admittances obtained by this method are compared with the results calculated by Shen. The calculated input impedances of the microstrip antenna agree fairly well with the experimental data for the substrate thickness of up to 0.048λ_g. The formulation of wall admittance presented here is easily applicable to arbitrarily shaped microstrip antennas.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"IEICE transactions on communications, E82-B(5), pp.760-767; 1999","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10826261","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168516","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":"Fujimoto, Takafumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Kazumasa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taguchi, Mitsuo"}],"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":"IEICEe82-b_760.pdf","filesize":[{"value":"420.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IEICEe82-b_760.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16249/files/IEICEe82-b_760.pdf"},"version_id":"cb4b5519-2c1f-4fa9-9dc3-5ad3cac1f51b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"microstrip antenna","subitem_subject_scheme":"Other"},{"subitem_subject":"wall admittance","subitem_subject_scheme":"Other"},{"subitem_subject":"spectral domain","subitem_subject_scheme":"Other"},{"subitem_subject":"cavity model","subitem_subject_scheme":"Other"},{"subitem_subject":"surface wave","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":"Wall Admittance of a Circular Microstrip Antenna","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Wall Admittance of a Circular Microstrip Antenna"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-09-03"},"publish_date":"2009-09-03","publish_status":"0","recid":"16249","relation_version_is_last":true,"title":["Wall Admittance of a Circular Microstrip Antenna"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T20:52:12.284081+00:00"}
