In this context, electronic beamforming systems have lower cost than mechanical ones. Knowing the uses of directive antennas and power dividers in electronic beamforming systems, this work aims at the design, simulation and measurements of these components at 5.8 GHz. Measurements with Power Divider showed very good return and insertion losses at 5.8 GHz: S11 = -23.5 dB and S21 = -3.8 dB. A printed dipole antenna was then fabricated, presenting -14.6 dB of return losses and a 2.82 dBi gain. Later, a 2-antenna beamforming front-end was implemented, proving the beamforming capability with the proposed devices. It also presented S11 = -15.7 dB, and a high directive gain (10.3 dBi). Since this is still a preliminary work, the results presented are very promising.","PeriodicalId":142095,"journal":{"name":"2016 1st International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"269 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128633435","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}

DAS architecture is divided into four layers. Main component is an Arduino Nano. Results showed that IoT and SWE combined with this approach improves effectiveness of observation processes and decision-making. Arduino Nano limitation provokes instabilities with Ethernet module if memory is massively used, but default source options grants four samples every hour, and a five observations queue in case of connection fault.
