The proposed tag antenna has an electrically small size of 45 mm × 45 mm × 3.2 mm. The under-loading loop-shaped feeder is employed for tuning the resonant frequency, where the inductive loop is found to be effective in bringing down the tag resonance to the useful UHF band and achieving conjugate impedance matching. From the simulation, the tag antenna's read distance on metal is found to be 33 m at the resonant frequency of 918 MHz.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124099260","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 consists of five rectangular coupled slots loaded with one variable capacitance in order to control the reflected phase. This variable capacitance is modelled with a lumped element, typically representing a surface mount varactor diode. A biasing line is also considered to isolate the RF signal from DC. Simulations demonstrate the superiority of this unit cell to its counterparts in terms of phase-range, bandwidth and robustness against oblique angle of incidence. In addition, numerical results show the ability of the unit cell to tilt the main beam of a circular array by 25° off broadside direction.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116019166","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}

Different from CDMA system, the wireless power transfer cannot be controlled because of the very low power efficiency. Only possible power transmission into the multiple user is based on the time division method with the maximum transmission power. So, in this paper, an efficient wireless power transmission system to multiple power receiver users based on the power pilot signal is suggested to satisfy the urgent power receiver and normal power receiver, together, which is a different time division assignment (DTDA) system in this paper. The power pilot signal transmits the authorized user information and the user's power level status information to the power transmission station. The power station transmits the wireless power to the user of the lowest power level in the first order and for the longest time. For the user identification of multiple users, the CDMA system is used, and the DTDA system is used to allocate power charging time differently to each user. This is meaningful in that power transmission is performed according to the power priority to multiple users. Finally, the power efficiency of the PLL-based RDA system is increased by conjugating the phase of the power pilot signal received from the user and transmitting it to the user. We like to propose these three systems and evaluate the performance through simulation by constructing the DTDA wireless power transmission system for supporting multiple users.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126940224","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 SWS is also capable of coupling with a higher phase velocity as compared with the conventional sinusoidal SWS and exhibits improved interaction impedance characteristics which make them ideal candidates for use in backward wave oscillators.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127626487","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}
