The proposed inverter, with lossless harmonic power, gives pure sinusoidal output voltage and current. It is aimed to be used with AC machines, sensitive appliances and home appliances even in the absence of main power supply. Also it can be used in high voltage direct current transmission line and for adjustable speed drives. The proposed microcontroller based inverter converts 12 or 24 V DC input to a pure undistorted 220V or 110V AC output. The total harmonic distortion of this inverter is less than 5% and it meets the IEEE standards, knowing that the most traditional inverters contain harmonics around 20% or more, which are useless to operate sensitive machines such as printers, faxes, photocopier machines and tripping circuits ...etc.","PeriodicalId":361750,"journal":{"name":"2013 13th Mediterranean Microwave Symposium (MMS)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125346466","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}

However, these parameters are very hard to simultaneously optimize, there is always a trade-off in between. In this paper, a Cylindrical Omnidirectional Slotted Waveguide Antenna (COSWA) is presented. The purpose of this paper is to provide an optimized version of circular slotted waveguide antennas by simply selecting the optimum position, number, shape and size of the slots within the waveguide wall. Such configurations are suitable to be used in Wireless internet distributing systems, Military radar applications and even oil drilling devices. Simulation results along with Experimental validations will be conducted at 2.4 GHz frequency demonstrating high effectiveness in terms of directivity and high gain given a reduced cost, simplicity and size.","PeriodicalId":361750,"journal":{"name":"2013 13th Mediterranean Microwave Symposium (MMS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130567798","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}

We show that open-loop resonators (OLRs) are capable to mitigate the induced noise. Electromagnetic coupling between two adjacent wires is considered to study the crosstalk noise, as well. Several methods such as the 3W rule spacing and the guard trace with distributed vias are applied to reduce the crosstalk noise. Simulation results show that OLR insertion between aggressor and victim wires reduce the crosstalk without degrading the wire response. The wire structures in the study are examined using ADS momentum tools.","PeriodicalId":361750,"journal":{"name":"2013 13th Mediterranean Microwave Symposium (MMS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121404580","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}
