Wireless power transfer (WPT) enables the use of rechargeable and thus smaller batteries, however it also requires additional space for the receiving coil. Depending on the location of the implant in the body, device area or volume can be more constrained. In this paper, we investigate multi-layer planar spiral coils via simulations. We study the impact of number of turns on the quality factor for multi-layer coils including coils with different number of turns in each layer (hybrid coils) and we offer recommendations on the approximate number of turns for having high Q values.","PeriodicalId":180534,"journal":{"name":"2018 IEEE Wireless Power Transfer Conference (WPTC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124551099","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}

The proposed structure includes a high gain 8-by-1 gap-coupled antenna array and a zero-bias Schottky diode rectifier circuit, to efficiently convert RF to DC signal. In order to further characterize the antenna array circuit, both structures (antenna and rectifier) are individually implemented on thin-film ceramic substrate ($varepsilon_{mathbf{r}} =$ 9.9, h = $mu$m), using an MHMIC (Miniature Hybrid Microwave Integrated Circuits) fabrication process. Then, they are joined together using low-loss wideband waveguide (WR12) to microstrip transitions in order to validate the investigated rectenna configuration. A maximum measured RF to DC conversion efficiency of 49.3 %, and sensitivity level of around −60 dBm were successfully achieved. These results make the proposed rectenna structure an excellent candidate for low power millimeter-wave energy harvesting.","PeriodicalId":180534,"journal":{"name":"2018 IEEE Wireless Power Transfer Conference (WPTC)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115321556","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}

Starting from low-frequency systems via magnetic coupling, the trend has been evolving toward high-frequency solutions, with a particular attention to the emerging 5G wireless communication equipment for the internet of things (IoT). In this respect, WPT has to face new challenges to become competitive at frequencies that will be of utmost importance in the near future, like the 28 GHz band. In this paper, we offer a rigorous combined electromagnetic/nonlinear circuit approach to evaluate the performance of a novel WPT system combining state-of-the-art time-modulated array (TMA) technology and high-performance metal-insulator-metal (MIM) diodes with fast switching time. Merging the advantages of TMAs with MIMs gives rise to a new family of low-power WPT devices, able to efficiently supply energy to the electronics used in IoT networks.","PeriodicalId":180534,"journal":{"name":"2018 IEEE Wireless Power Transfer Conference (WPTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123697088","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}

Tx/Rx isolation is obtained through the generation of the 2nd harmonic signal. The proposed architecture design is based on a high isolation diplexer with a single (dual band) antenna as opposed to a traditional design using two-antenna isolation. Such an architecture relaxes the stringent design requirements of antennas in traditional architectures. Subsequently, antennas with enhanced performance can be utilized without resorting to compromise. Measured results of the proposed transponder circuit have shown improved performance over the state of the art counterparts. The conversion loss is about 20.2 dB at -30 dBm input power, which shows more than 10 dB better than previous work.","PeriodicalId":180534,"journal":{"name":"2018 IEEE Wireless Power Transfer Conference (WPTC)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124594309","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}

By considering nonlinear resonance properties and introducing complex variables, the coupled-mode models of WPT systems with Duffing resonators are derived. Thereafter, transfer performance in the steady state is investigated in an explicit way according to coupled-mode theory (CMT) as well as the parameter conditions of an exact PT symmetric phase. In comparison with PT symmetry-based WPT systems with linear LC resonators, WPT systems with PT symmetric Duffing resonators exhibit combined features of distance and resonance detuning insensitivity. Finally, a system is designed to maintain constant transfer efficiency of 84% with a resonance detuning tolerance of nearly 5%, which is confirmed by simulation results.","PeriodicalId":180534,"journal":{"name":"2018 IEEE Wireless Power Transfer Conference (WPTC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129092345","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}

Two methods to eliminate the MP problem are demonstrated. Then a delay time based high precision on/off control method is proposed. The new controller senses the current passing through MOSFET and generates the gate driving signals to control the next operating cycle of the active rectifier. Under a 13.65 MHz wireless power transmission test platform, with the same rectification parameters, the experimental results show that the quiescent power consumption of the proposed controller is reduced by 2/3 compared with that of the comparator-based structure. The reverse current is almost eliminated because the on/off control precision reachesps level. Thus, the conversion efficiency of the rectifier is improved significantly.
