The structure proposed is based on dipole like structures and three of such dipoles conforms a tag. Several chipless RFID tag prototypes were fabricated on PET substrate and measured within the frequency band from 2 GHz to 5 GHz. In contrast to the already reported printed tags where inkjet printing is used, the proposed tag is fabricated using screen printing techniques which enable fast mass production of tags in a very short time with thick conductive tracks of ~10 um. A good agreement between simulation and measurement was obtained and a reading distance up to 1 m is obtained with a transmission power of 3 dBm. The obtained results confirm the use of low cost printed tags for mass market applications.","PeriodicalId":22362,"journal":{"name":"The 8th European Conference on Antennas and Propagation (EuCAP 2014)","volume":"19 1","pages":"2950-2954"},"PeriodicalIF":0.0,"publicationDate":"2014-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81767666","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 propose a system that minimizes this standby power in home automation or multimedia systems. This system is composed of a 2.45 GHz emitter and a receiver with a sensitivity of -22 dBm (higher than a receiver directly supplied). This receiver implies a difficult link budget contrary to classical receiver sensitivity (-80 or -90 dBm). That is why the antennas have a very important role because they must be totally optimized to avoid link budget degradation. Moreover, this system is dedicated to mass market applications. As a result, all the materials and manufacturing process concerning the antennas must be as versatile as possible to be integrated in different cases and cheap to manufacture. To satisfy these objectives, we present a generic design of parasitic element antennas that are suited to both the emitter and the receiver. Measurements results are presented to validate the design.","PeriodicalId":22362,"journal":{"name":"The 8th European Conference on Antennas and Propagation (EuCAP 2014)","volume":"10 1","pages":"1390-1392"},"PeriodicalIF":0.0,"publicationDate":"2014-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82315959","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}

Antenna consists of coupling monopole resonators which are extended from the feed and main ground plan to accommodate integration with circuit board of mobile handset. Antenna can easily be fabricated with the help of extended line and ground without disturbing main circuit board of handset, considering the presence of protruded components over circuit board. The antenna design uses fork-shaped monopole coupling resonators extended from active element and ground plane. These resonators along with prolonged length from patch and ground, as a function of resonating wavelength, control the bandwidth of antenna. Monopoles driven from patch and ground contribute the lowest and higher order resonant modes to form three wide operating bands centered at about 1800, 2500 and 5200MHz to cover GSM1800/1900/UMTS/LTE2300/2500. The results of this study confirmed that extended planner monopoles couple to form lower and higher resonant modes.

The proposed junction is formed as a quasi periodic arrangement of N unit cells. Each unit cell is realized as a cascade of short cylindrical ferrite coupled lines with reactance circuit composed of series capacitors and parallel inductors. The left-handed cylindrical junction with π/4 Faraday rotation was designed with the use of own software. Promising results concerning size reduction of the ferrite junction in comparison to known in literature conventional one were obtained. In order to examine nonreciprocal properties of the designed junction its calculated scattering parameters were used to predict the behavior of three-port circulator. The obtained results confirmed usefulness of the proposed left-handed cylindrical junction in the design of Faraday nonreciprocal devices.","PeriodicalId":22362,"journal":{"name":"The 8th European Conference on Antennas and Propagation (EuCAP 2014)","volume":"1203 1","pages":"885-888"},"PeriodicalIF":0.0,"publicationDate":"2014-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76370083","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}
