Among the WPT technologies developed so far, magnetically coupled resonance (MCR) techniques have gained much attention to potentials for mid-range power transfers. However, misalignments between transmitters and receivers have become one of the major obstacles in improving the power transfer efficiency. This paper presents our recent progress in developing new MCR-WPT systems in mitigating the misalignment effects for wireless power transfers. Prototypes are developed and tested to demonstrate the effects of our proposed systems.","PeriodicalId":128207,"journal":{"name":"2018 18th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134278100","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}

They are applicable to high-field operations, in which the geometrical dimensions of the coil become comparable to the Larmor wave-length. The circuit-based analysis utilizes the characteristic properties of circulant matrices that describe periodic structures with ring-type coupling. It allows for controlling the coupling without the need of minimizing or eliminating it. It also gives useful equations for the calculation of the coil loading, which is needed for the optimization of its operation in both transmitting and receiving scenarios. The paper is essentially of a fundamental nature and presents and/or revisits physical insights and useful equations.

The bandpass filter is designed using 7th order short circuited stub filter. Then, the first short circuited stub is replaced with two sections of open circuited stub to exhibit the transmission zeros at lower/higher stopband. The varactor diode is placed at the J-shape open circuited stub to produce tunable transmission zeros by tuning the voltage on the varactor diodes with range from 0 V to 6 V. The U-shape notched response produced high selectivity and attenuation at resonant frequency of 5.2 GHz. The fabricated result shows good agreement with the simulated results. This type of filter is very useful for applications where the undesired signals and interference will be eliminated within the passband response such as medical electronic, radar and 5G applications.","PeriodicalId":128207,"journal":{"name":"2018 18th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130575207","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}
