The proposed slot antenna has a narrow slot which is directly constructed in the metal housing of the ultra-book, and then feeding the antenna using a 50-Ω microstrip line which is printed on a 0.4 mm FR4 substrate. Through the adjustment of the dimension of the slot and the length of the microstrip line, good impedance matching and dual-band operation bandwidth was obtained. Prototypes have been successfully implemented, and experimental results show that the good antenna efficiency and radiation performance were obtained. Due to it can be integrated with the metal housing of the wireless device, the proposed antenna is very suitable for the WiFi antenna application of a mobile computer, such a notebook or an ultrabook. Details of the proposed antenna and experimental results are presented and discussed.","PeriodicalId":354277,"journal":{"name":"2014 International Symposium on Antennas and Propagation Conference Proceedings","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126968875","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}

Measured results indicate that the 3dB-axial-ratio bandwidths of the three prototypes, centered at 0.9, 1.4, 2 GHz, are 26, 37, and 32 %, respectively.
