Lossless FR4 is used as the substrate with a permittivity of 4.3, and the project is simulated based on CST STUDIO SUITE. The size of the proposed antenna is $26times 30times 1.536 text{mm}^{3}$. Rectangular slots, H-shaped slot with inner gap and partially covered ground plane are three main design techniques applied. The resonant frequency, S-Parameters and bandwidth in each area of the spectrum are three main criteria used to assess the antenna's performance. Referring to the optimization of the design, antenna parameter analysis is conducted by plotting series of $S_{11}$ curves representing variation in the parameter that matters to achieve the desired specifications. It turns out that the first resonant frequency in 5.8 GHz ISM spectrum is 5.76 GHz with a bandwidth of 160 MHz covering 5.696 ∼ 5.856 GHz. The second resonance in SHF spectrum is at 26 GHz with a broad bandwidth covering 22.4 ∼ 31.3 GHz.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116266253","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}

Apart from the motion detection on frequency-domain such as heartbeat rate and respiration rate, Doppler Radar sensors can be utilized to obtain the vital-sign in the time-domain to get more detailed information. To overcome the drawbacks of traditional phase demodulation which has to find direct current (DC) offsets for accurate detection, we propose the improved arc-chord approximation approach to avoid the complex and unstable result in linear demodulation. The crucial fitting procedure in the arc-chord approximation is innovatively implemented by the mean of vector phase (MVP) method. Both theory and numerical simulation are conducted in this paper to show the effectiveness of our method.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127386594","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}

For considering the safety and comfort, the microwave radiation power and imaging time are both preferred to be less. However, it results in an issue of artifacts and noise due to sparsely spatial sampling and relative lower SNR of TA signals. Aiming to overcome this problem, deep learning-based method is an emerging technique. In this work, we evaluate the artifact removing performance of a network based on fully dense U-Net architecture. The results show that FD U-Net network could effectively remove the artifacts from the TA images and improve the image quality.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131359730","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}

Here, a tunable spoof plasmonic meta-waveguide (SPMW) is constructed to realize ultra-sensitive temperature sensing. More importantly, compared with other devices, this sensor affords visual temperature imaging, which provides the precise monitoring of large-area temperature. All these advantages are due to the ingenious configuration of spoof plasmonic meta-waveguide and material characteristics.
