This type of coupling eliminates the competition for surface space between the antenna elements and the feed network. Besides, the ground plane shields the antenna half-space from spurious radiation emitted by feed lines and active devices. The array antennas is designed on a high dielectric constant substrate (εr = 9.9), which demonstrates the feasibility of integration of such antenna structure into monolithic circuits. The array antenna is the key component in a smart antenna system used in a prototype of broadband wireless LAN system operating at up to multi-Gb/s.","PeriodicalId":213759,"journal":{"name":"2009 IEEE Antennas and Propagation Society International Symposium","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123111514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
