It is composed of a zeroth-order loop loaded periodically with mu-negative transmission line (MNG-TL) and a circular patch located in the center of loop. The MNG-TL loop based on the fundamental infinite wavelength property allows current along the loop to remain in phase and same magnitude so that a highly efficient and miniature loop antenna with omni-directional pattern in azimuth plane at low frequency band for on-body communications is generated. On the other hand, a unidirectional pattern in elevation plane at upper frequency band for off-body communications is also obtained by circular patch simultaneously. In order to improve the pattern in azimuth plane, a split ring resonator (SRR) element is used to direct the electromagnetic field propagation. By placing a single SRR at the near field of the loop in different location, the mechanic of function between SRR and loop is also presented.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"1 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76626166","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 planar horn-shaped structure is applied on the antenna to realize directional radiation and a ridge type slow-wave structure is introduced to reduce the antenna size. Simulation and measuring results meet well. The antenna has the advantages of good directivity, easy fabrication and low cost. So it has the potential to be applied to wireless device online test.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"274 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76798326","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 fibrous, flexible supercapacitors fabricated based on this hierarchically nanostructured material achieved excellent electrochemical performance. With an areal capacitance of 60.02mF/cm2 (two-electrode system) in aqueous electrolyte, this structure displayed an areal capacitance three times than that of pure-graphene supercapacitors.
