In considered crystals a low dislocation density (5×103 cm-2) is attainable. High crystallinity is manifested by extremely flat crystal lattice and very narrow (FWHM=16 arcsec) X-ray rocking curves measured for (0002) plane.

The concept is validated with electromagnetic simulations based on the finite-difference time-domain method, where scattering parameters are computed.

These factors cause deviation of the antenna performance from the ideal, and can lead to unexpected performance issues for devices such as wireless sensor nodes. Accurate radiation pattern characterisation requires a reflectionless environment, and a rigorous measurement technique. In this paper, we present the results of a rigorous measurement technique carried out at the UK National Physical Laboratory for the radiation pattern characterisation of embedded radios emitting modulated signals. Using a half-wave dipole antenna a pattern measuring process, which is robust to modulated and bursty signals, is presented and validated against a traditional pattern measuring method. The technique is then applied to a commonly employed wireless sensor network (WSN) platform, the SunSpot, with the influence of various mounting configurations presented.","PeriodicalId":425104,"journal":{"name":"2012 19th International Conference on Microwaves, Radar & Wireless Communications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132071553","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}

The coplanar structure has been selected to improve the grounding and also to remove the effect of the fillers on the transmission line. The two transmission lines differ by their bottom metal layer pattern. In the first transmission line the bottom metal is solid ground while in the second transmission line the bottom metal layer is used as a shield. The transmission lines are optimized for different parameters like insertion loss, inductance per unit length and size. Also to justify the electromagnetic simulated models of the transmission lines, different transmission lines have been realized and measured. The characteristics of the transmission lines are extracted from the measurement results. Comparison of the model and the measured results shows a good agreement up to 100 GHz. Finally, two 60 GHz amplifiers in 90 nm CMOS technology were designed based on these transmission lines.","PeriodicalId":425104,"journal":{"name":"2012 19th International Conference on Microwaves, Radar & Wireless Communications","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126595167","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}
