The proposed antenna is well matched for both GSM 900 and 1800 bands and provides decent gain for both the bands (1.67 and 3.27 dBi at 900 MHz and 1800 MHz respectively). The antenna is printed with silver ink on a 3D printed polymer based package. The package houses the GSM electronics and the battery. By optimizing the antenna arms width and length, a near-isotropic radiation pattern is achieved. Unlike the published isotropic antennas which are either single band or large in size, the proposed antenna covers both GSM bands with required bandwidth and is only half wavelength long. The design is low cost and highly suitable for various GSM applications such as localization, in additional to conventional communication applications.","PeriodicalId":264754,"journal":{"name":"2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134243233","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}

Compared with previous FSSs, the proposed structure has promising miniaturization features. The array element is implemented by using vias to connect structures on two surface layers. The dimensions of the proposed array element are only 0.035λ×0.035λ. The top layer is constructed by four spiral-shaped structures; the bottom is made of four square-shaped patches. They are connected in series by vias. In so doing, the values of the resonant component values are increased; thus the resonant frequency is shifted downwards. The frequency response is insensitive to the oblique incidence angle. Also, the proposed design is symmetric rotationally on the xy (the surface) plane and can be applied for circular polarization applications.","PeriodicalId":264754,"journal":{"name":"2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133571742","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 was shown through simulation and measurement that a high water content tumor in the immediacy of an antenna implanted in a low water content tissue, such as breast tissue, will cause resonant frequency and bandwidth changes alongside a reduction in radiation efficiency. These effects were shown to increase as the tumor increased in volume with a maximum resonant frequency shift of 3.2% and a reduction in measured radiation efficiency relative to the diameter of the tumor of 0.1 dB/mm. Antennas with dual resonance are shown to mitigate resonant frequency variation effects.","PeriodicalId":264754,"journal":{"name":"2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123776293","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}
