The basic idea is that coupling between two transmission lines is present at two points only. The coupling is realized by SMD capacitances soldered to the lines. The presented type of couplers is in close relation to two hole waveguide coupler. The proposed couplers have narrow bandwidth. Several couplers with 3, 6, 10 and 15 dB couplings have been designed and realized at frequency 1.3 GHz. In each case directivity is better than 30 dB. Couplers are planar, compact and easy to realize.","PeriodicalId":354299,"journal":{"name":"2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON)","volume":"18 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":"116861697","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}

This paper presents a design technique for meta-structure planar directional couplers that can achieve a wide range of arbitrary coupling ratios. Replacing the conventional transmission lines with a composite right/left-handed (CRLH) meta-structure, the proposed technique enables the use of one design parameter to achieve different coupling ratios. To demonstrate the technique, a 90° directional coupler operating at 2.45 GHz has been designed, fabricated and characterized. Simulated and measured results show good agreement.","PeriodicalId":354299,"journal":{"name":"2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON)","volume":"56 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":"123899725","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}

One of the possible solutions is the implementation of cooperative positioning techniques. The following paper describes a cooperative ultra-wideband positioning system which calculates tag position from TDOA and distance between tags measurements. In the paper positioning system architecture is described and an exemplary transmission scheme for cooperative systems is presented. Considered localization system utilizes an Extended Kalman Filter based algorithm. The algorithm was investigated with simulations and experiments. Conducted experiment consisted in fusing results gathered from typical TDOA positioning system infrastructure and ranging results obtained with ultra-wideband radio modules. The research has shown that the use presented cooperative algorithm increases positioning precision.","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":"131017432","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}

Electrical and mechanical axis are not co-incident, making alignment procedures important. A prime reason for publication is that acceptable results can already be obtained with a relatively small NF scan-plane. A comparison is shown with results obtained 25 years ago.

Source/load-pull setup is used to extract the optimum source/load impedances across 1.1 – 2.7 GHz. The harmonics impact is considered to improve the power amplifier efficiency. Utilizing the characteristics of FET transistor leads to modify the optimum fundamental load impedances of the low frequency range, which have higher gain compared to high frequency range, and minimize the influence of the higher harmonics. This method results in a measured minimum output power of 43 dBm with a drain efficiency ranged between 65 % to 75 % and a flat gain of 10.5 ±1 dB over the desired band.","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":"128785153","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}
