The implementation of the slot can not only create its own notched band, but also enhance the filtering performance at the other notched band generated by EBG structures. This is caused by the increased current density in the two ends of the slot. The location of the two notched bands are determined by the position and size of the EBG and the length of the slot, respectively. However, the parameters of the EBG structures and slot has little effect on the antenna performance. The simulated results demonstrate that the proposed antenna exhibits a good wideband radiation performance from 2.64 to 12.9 GHz along with two separated notched bands at WLAN (4.8-5.9 GHz) and X-band downlink satellite communication band (7.1-7.8 GHz). As a result, the proposed design is a promising candidate for modern UWB antennas.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133828280","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}

Kan","doi":"10.1109/IMBIOC.2019.8777742","DOIUrl":"https://doi.org/10.1109/IMBIOC.2019.8777742","url":null,"abstract":"Monitoring of the vital signs including heartbeat, respiration and blood pressure for long duration is critical for driver alertness, smart home, E-health and Internet of Things (IoT), especially when the user takes a seat as in the cases of seniors, patients, and car drivers. The sensing system should be integrated into the seat cushion and “invisible” to the users to provide continuous, comfortable and convenient monitoring. However, current vital-sign sensing technologies often require skin-touch electrodes or external readers with clear line-of-sight, and are hence difficult to be deployed into the chair setup. Piezoelectric, accelerometer and ultrasound sensors can suffer from mechanical damping in soft cushion and limited sensitivity. The radar-based system provides non-contact measurements based on signal reflection from body surfaces, but high areal resolution to accommodate multiple observation points on one user often incurs significant system cost. In this work, an active near-field coherent sensing (NCS) system is integrated into generic seat structures to assess the heartbeat, respiration and blood pressure of the occupant. With the improved balancing bridge design, the weak cardiopulmonary signals from the back and the femoral pulse from the thigh area can be accurately detected for the pulse transit time and the derived blood pressure. Variation of sensing positions due to different postures and body sizes is investigate for robust placement considerations.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134216584","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 proposed antenna uses four angle-adjustable $lambda/4$ ground stubs to cancel out the E-plane coupling between two adjacent elements. Furthermore, the dumbbell-shaped defected ground structure is inserted to reduce the H-plane coupling. The prototype antenna was fabricated in this work where edge-to-edge separation of the antenna elements were kept at $0.072lambda_{0}$. Experimental results verify that the proposed design effectively suppresses the mutual coupling of the dual-band and dual-polarized antenna. The isolation of the antenna at 5.2 GHz and 6 GHz is increased by 18.1 dB and 20.8 dB, respectively.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131548679","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}

By electrostatic field simulation, the distribution of electric field in the bounded wave simulator under experimental conditions was analyzed. The results show that the local field enhancement in space is obvious. The electric field on the surface of the upper electrode under the loading voltage is obviously greater. Furthermore, the SAR value of bioelectromagnetic dose was analyzed. Under 1 pps working operation, 150 kV loading voltage and PML boundary condition, the SAR value is calculated to be $6times 10^{-5} mathbf{W}/mathbf{kg}$. Besides, the bioelectromagnetic dose under non-PML boundary condition was explored. The results show that the SAR value at high voltage electrode is maximal. The difference between the maximum and the minimum is 7 dB, which is much more than the dose deviation limit of 3 dB. The results above show that the bioelectromagnetic dose characteristics of the bounded wave simulator under nanosecond pulses are correlated with the position in the simulator. Biological experiments should be carefully designed according to the results of dose analysis.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125331172","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}
