The distance between the patch antenna and TL is set to be 2mm. For obtaining a lower mutual coupling between the used antenna and the TL, a G-shaped defected isolation wall is designed and vertically placed between the used patch antenna and TL. The simulation results gave a conformation that the mutual coupling is decreased by 25 dB, and the performance of the patch antenna and microstrip transmission line are not affected.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"57 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":"125127479","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 calibration process of the electromagnetic positioning system mainly compensates and eliminates the static error, and relates to the equipment and the environment around the electromagnetic positioning system. The equipment used in the experiment was Pholhemus's 3SPACE FASTRAK, which was used in a training system. In this paper, taking into account factors such as algorithm complexity and predictability, second-order polynomial fitting and third-order polynomial fitting algorithms are used to compensate for position and orientation errors of the sensor. Experimental and simulation results show that the third-order polynomial fitting has greatly improved the position and direction accuracy.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"50 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":"124331546","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}

Simulations and experiment results have showed the change of the focal spot on the antenna axis and target plane each when the antenna feed is located at the focal point and offset-focusing.

One major problem affecting the performance of an RFID tag is the variation of feed-point impedance when the antenna is attached onto media with different dielectric permittivity. It is proposed to switch between different feed-points of the antenna to reduce feed impedance mismatch. This study identifies the worst-case level of reflection coefficient magnitude of dipole antennas with a single feed and with two feeds, while varying the positions of the feed points, for a scenario where the antennas are attached to a dielectric half-space of relative permittivity ranging from 1 to 50.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"30 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":"124773820","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 is made of two planar inverted-F antennas (PIFAs) placing side-by-side. Two pairs of notches are created on the top surface of the patches for tuning the tag's resonant frequency. The antenna impedance can be easily matched with the chip impedance at different tag's resonances. It is found that the realized gain of the tag antenna can be improved by broadening the vertical arm width. With the use of 4W EIRP, the tag antenna is found to be able to achieve a measured read range of 8.7 m on metals, with little fluctuation in the tag's resonance for all cases.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"78 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":"126305008","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}
