A reduced size reflectarray unit cell is properly synthesized in order to extend the antenna beam scanning capabilities within a wider angular region. The radiating structure is accurately optimized to provide a full phase tuning range by adopting a single varactor load as phase shifter element. A 0.46<jats:italic>\u03bb<\/jats:italic>-reflectarray cell is designed at the frequency of 11.5\u2009GHz, obtaining a phase agility of about 330\u00b0. The cell is successfully adopted for the design of a<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mn>21\u2009<\/mml:mn><mml:mo>\u00d7<\/mml:mo><mml:mn>\u200921<\/mml:mn><\/mml:math>reconfigurable reflectarray. The antenna is numerically tested for different configurations of the varactors capacitance values, and good beam-steering performances are demonstrated within a wide angular range.<\/jats:p>","DOI":"10.1155\/2013\/325746","type":"journal-article","created":{"date-parts":[[2013,7,24]],"date-time":"2013-07-24T23:33:43Z","timestamp":1374708823000},"page":"1-7","source":"Crossref","is-referenced-by-count":9,"title":["Tunable Reflectarray Cell for Wide Angle Beam-Steering Radar Applications"],"prefix":"10.1155","volume":"2013","author":[{"given":"F.","family":"Venneri","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria Informatica, Modellistica, Elettronica e Sistemistica, Universit\u00e0 della Calabria, 87036 Rende (CS), Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Costanzo","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Informatica, Modellistica, Elettronica e Sistemistica, Universit\u00e0 della Calabria, 87036 Rende (CS), Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Di Massa","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Informatica, Modellistica, Elettronica e Sistemistica, Universit\u00e0 della Calabria, 87036 Rende (CS), Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","first-page":"321","volume":"12","year":"2000","journal-title":"Lincoln Laboratory Journal"},{"key":"2","year":"2008"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1049\/iet-smt.2010.0132"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/LMWC.2005.850561"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2007.895586"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1049\/el.2011.3691"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/290285"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2012.2226229"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/LAWP.2005.852583"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1049\/el:20030201"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1163\/156939306777442926"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.2528\/PIER07031903"},{"key":"15","year":"1997"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1049\/el:20062492"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1163\/156939308786390247"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/846017"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2013\/325746.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2013\/325746.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2013\/325746.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,18]],"date-time":"2016-08-18T17:02:44Z","timestamp":1471539764000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jece\/2013\/325746\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":16,"alternative-id":["325746","325746"],"URL":"https:\/\/doi.org\/10.1155\/2013\/325746","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"value":"2090-0147","type":"print"},{"value":"2090-0155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013]]}}}
