Hollow solenoidal coils are used as resonant coils extensively in engineering projects which are usually analyzed based on magnetostatic fields. In practice coils are often excited by alternating currents, and it is particularly significant to carry out studies on the time-harmonic electromagnetic solutions to solenoidal coils. In this study, the alternating magnetic vector potential is derived from Maxwell's time-harmonic equations, and the analytic expressions are established for coaxially symmetric solenoidal coils firstly. Then the expressions for the electric field intensity and the induced voltages of the coils are deduced, and the field-circuit coupling equations for WPT which show the specific constraint relationship between the input and output variables are obtained. Finally, the results are verified by experiment. The transmission characteristics and the variation of the input and output variables under different coils' spans can be described by the equations when the coils' structures and sizes are given, which have some significance for WPT design.","PeriodicalId":164534,"journal":{"name":"2015 IEEE International Wireless Symposium (IWS 2015)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122792258","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}

A key merit of the filter configuration is that the position of the transmission zeros can be conveniently controlled whereas the bandwidth is fixed. The bandpass filter consists of two half-wavelength resonators, two open circuited uniform impedance resonators and one stepped impedance resonator. With five reflection zeros generated in the passband, six controllable transmission zeros are introduced to sharpen the passband skirts. Without coupling gaps between resonators, the new filter show low insertion loss and is easy for fabrication. To verify the design concept, one filter example has been designed, fabricated and measured. Good insertion/return losses, flat group delay, sharp transition and simple topology are achieved as demonstrated in both simulation and experiment.","PeriodicalId":164534,"journal":{"name":"2015 IEEE International Wireless Symposium (IWS 2015)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133665042","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 TPD antenna has a measured isolation performance better than -25 dB over the working bandwidth of 2.35-2.53 GHz. Furthermore, the correlation coefficients of the TPD MIMO channel are measured in a lossy and non-lossy reverberation chamber, individually. In both the transmitting (Tx) and receiving (Rx) end, the average values of the correlation coefficients in the two cases are about 0.33 and 0.11 respectively, which indicates that the TPD MIMO antenna has a good multiplexing performance. More importantly, we have found that except for the signal correlation, the relative path loss is also very important in the MIMO capacity comparison in different propagation scenarios. It is shown that in the lossy and non-lossy reverberation chamber, the TPD antenna have similar multiplexing performance; however, if the relative path loss is included, the MIMO capacity in the lossy reverberation chamber is obviously smaller than that in the non-lossy one, with the same Tx and Rx antenna.","PeriodicalId":164534,"journal":{"name":"2015 IEEE International Wireless Symposium (IWS 2015)","volume":"602 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116342311","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}
