In order to increase the reliability of consumers supply, the additional power distribution substations are commonly installed, which in time become surrounded by the expanded residential areas. In consequence, their presence increases the health concern of residents, having in mind that power substations are known sources of the low-frequency electromagnetic field (EMF). Therefore, the continuous monitoring of EMF is expected, as well as the adequate assessment of corresponding exposure of population in vicinity of such objects. In this paper, the test utilization of a modern, wireless sensors-based monitoring network, the Serbian Electromagnetic Field Monitoring Network - SEMONT, was considered for the advanced low-frequency EMF monitoring in the upcoming smart cities environment. The case study and test measurements were performed in vicinity of the power substation “NS7 - South Telep”, located in the city of Novi Sad, the Republic of Serbia, where the acquired results emerge to be far below the Serbian prescribed reference levels.","PeriodicalId":354299,"journal":{"name":"2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124704037","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}

When tested with continuous wave signals the PA shows a saturated output power higher than 37 dBm, with an efficiency larger than 60% and an AM/AM and AM/PM distortions lower than 2 dB and ±1 deg, respectively.

The unit UWB antenna element is of compact size with the dimensions of 22×24 mm2. The proposed MIMO antenna structure consists of two pairs of dual polarized rectangular shape UWB monopole antennas. A simple decoupling structure (DS) comprising of rectangular stubs is optimized with several full wave simulations to improve the isolation among the antennas. The proposed MIMO system exhibits reflection coefficient whose value is less than -10 dB from 4.5 GHz - 11.5 GHz. Different important parameters such as radiation characters, time domain received signals from each antenna element, electric field distribution, envelop correlation coefficient and diversity gain are calculated, analyzed and compared. The diversity antenna system with decoupling structure has shown a significant better performance compared to the system without decoupling structure.","PeriodicalId":354299,"journal":{"name":"2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130555177","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}
