Crosstalk is a form of noise. It is a major concern in electronic design. Indeed, as our communication systems grow in size and complexity, so does the crosstalk suppression issue. And with it, the complexity and/or the price of the solutions. Through this thesis, I would like to present you my piece of solution to effectively reduce crosstalk at low cost within multichannel transmission systems.\nThe Pie-Chart antenna concept is a simple yet effective method of designing arrays of antennas so that emitters and receivers can communicate through highly independent transmission channels. In a nutshell, a Pie-Chart channel (or pie channel) is defined by its order of symmetry around a longitudinal axis, thus describing an axis-symmetric azimuthal emission/reception diversity pattern. A different order of symmetry around the same axis defines a physically different channel. Every pie arrays of the same order of symmetry around this axis can communicate with each other. While transmissions from arrays of a different order are heavily rejected through a passive form of destructive interference noise cancellation. This concept is expendable past the limited frame of electromagnetism (acoustic, vibrations and wave-signals in general) and its applicability goes beyond the sole field of wireless transmission.\nHowever very intuitive to understand and apparently fruitful in term of its applicability, the result of preliminary state-of-the-art researches revealed that this concept have seemingly not already been reported up to present (too trivial to be treated?). There-fore, within the course of this PhD. I developed an electromagnetic model describing the theoretical operation of the presented concept. I set and realized several experiments which results show good agreement with the model’s predictions. I discussed how could exiting devices benefit from the proposed solution. And finally, I conceptualized new applications made possible by the Pie-Chart antenna concept. Through the hereby manuscript, I will present you a synthesis of this journey and its major outcomes.\nThis thesis is my modest contribution to the accretion and the transmission of mankind knowledges. As a matter of fact, it is written so that to be understandable by anyone having knowledges in euclidean geometry, basis in electricity, linear algebra as well as differential and integral calculus. May this humble piece of work be wisely used to your fulfillment.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Division of System Engineering Mie University, Japan","subitem_description_type":"Other"},{"subitem_description":"68p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲工学第1864号"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"item_7_version_type_15":{"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":"Jean-Philippe, Douarville-Blaise","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-11-06"}],"filename":"2017DE005.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2017DE005.pdf","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/2001035/files/2017DE005.pdf"},"version_id":"08c186eb-bccd-4dff-8629-80f1b4693b7a"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Eliminate Crosstalk Using Symmetry in MIMO Arrays of Inductive Antennas: The Pie-Chart Antennas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Eliminate Crosstalk Using Symmetry in MIMO Arrays of Inductive Antennas: The Pie-Chart Antennas","subitem_title_language":"en"}]},"item_type_id":"7","owner":"15","path":["859"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-11-06"},"publish_date":"2024-11-06","publish_status":"0","recid":"2001035","relation_version_is_last":true,"title":["Eliminate Crosstalk Using Symmetry in MIMO Arrays of Inductive Antennas: The Pie-Chart Antennas"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-11-06T00:30:56.268134+00:00"}
