Recharging of such systems is often delivered by rectifying antennas. In this paper we propose an energy harvesting system for IEEE 802.11 standard that can work within Wi-Fi frequency range (2412 MHz-2472 MHz and 5160-5825 MHz). The proposed system is based on phased patch-antennas with focusing and scanning of electron beam. The use of such a system increases the gain, power characteristics and, consequently, the productivity of a smart energy harvester compared to energy harvesting systems with a single antenna.","PeriodicalId":218866,"journal":{"name":"2022 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116672793","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}

It is shown that the test exposure of a pulsed current of increased density, which does not lead to the destruction of the structure, makes it possible to identify and reject LEDs with an abnormally high rate of change in the luminous flux at the initial stage of current tests and, thereby, equalize the degradation rate of LEDs in the sample.","PeriodicalId":218866,"journal":{"name":"2022 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114891149","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}
