This is achieved by merging the different radiation modes of the antenna together within a single operating band, in contrast to the conventional procedure of covering the whole band with a single radiation mode. Using this method a single antenna can provide radiation pattern diversity across the operating band without an external switching mechanism. This proposal improves the connectivity significantly when the link is dynamic. The channel selection algorithm can be modified accordingly where the channels can be pre-mapped for expected Direction of Arrival (DoA) of specific links. Depending on the standards assumed, a certain number of channels are used for directing the maximum radiation at φ = 0°, θ = 8°, while the rest is suitable for directing the main beam at φ = 0°, θ = 72°.","PeriodicalId":306938,"journal":{"name":"2015 IEEE Radio and Wireless Symposium (RWS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114026375","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}

T-match technique is utilized to achieve simultaneously wideband input and output impedance matching, wideband power gain (S21) and wideband NF at both 60-GHz-band and 77-GHz-band. The LNA consumes only 9.99 mW, achieving S11 better than -10 dB for frequencies of 57.6~81.8 GHz, and S12 better than -29.1 dB for frequencies of 10~110 GHz. Additionally, high and flat S21 of 11.2±1.5 dB is achieved for frequencies of 57.9~80.4 GHz, which means the corresponding 3-dB bandwidth is 22.5 GHz. Furthermore, the LNA achieves minimum noise figure (NF) of 4.8 dB at 76 GHz and NF of 6.2±1.4 dB for frequencies of 76~84 GHz, one of the best NF results ever reported for a W-band CMOS LNA.
