By employing an RLC series network between the gate and drain of the transistor, the LNA circuit can operate at a wide frequency band while maintaining a stable impedance due to feedback of the RLC series network. In addition, a T-matching network is introduced as the inter-stage matching to increase power transfer and achieve frequency filtering. Using a standard 0.25um phemt GaAs process, the proposed LNA exhibits 14 dB gain and a noise figure of 2.3 dB to 3.5 dB from 6 to18 GHz, while the input and output return loss are less than 10 dB, respectively.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 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":"131268592","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}

Two on-body channel parameters are analyzed which are path loss magnitude (PL) and rms delay spread $(boldsymbol{sigma}_{boldsymbol{tau}})$. The compact wearable antennas are placed on the wrist in two different locations (outer and inner wrist). Five limb movement activities are performed by real human subject in an indoor environment related to forward, backward, sideways motion and arm bending. It is observed that different position of the arms lead to different channels links for each activity considered. The LOS/NLOS channels generally have a PL magnitude of 45-55/60-65 dB and $boldsymbol{sigma}_{boldsymbol{tau}}$ of 0.5-5/6-35 nsec respectively. Arm bending activity results in minimum PL (48/60 dB) and $boldsymbol{sigma}_{boldsymbol{tau}}$ (0.5-2/6-15 nsec) for LOS/NLOS links as the distance between the two antennas (placed on the wrist and shoulder) is least.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"115 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":"132847082","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 ICB can connect with a standard coaxial connector to microwave lab equipment and uses a spring levered interface with elastomer conductive pins to connect to the disposable chip. With the spring-system, a new microwave-microfluidic chip can be mounted reliably on the setup in a couple of seconds. The high-frequency interface within the ICB is protected from the environment by an enclosure having a single slit for mounting the chip. The gold-on-quartz technology and casting of polydimethylsiloxane was used to develop an interdigital capacitor (IDC) for microwave sensing and heating for continuous flow microfluidics. Different isopropyl alcohol-water mixtures were flushed through the channel over the IDC and sensed based on the measured reflection coefficient measurements of the interconnected IDC on quartz. Using calibration techniques, the dielectric properties were extracted and good agreement with values in literature was obtained. At last, a deionized water sample of $2mu mathbf{L}$ was heated with heating rates of 50° C/s.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"69 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":"131225479","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}

In order to investigate the frequency effect on the detection performance of the vital signs, the muscle sphere is used to emulate the human heart organ to compute the scattering field of the incident wave radiated from the Doppler radar. The radar cross section (RCS) can then be calculated from the receiving power by radar equation. In the validated experimental measurement, a pig heart (to simulate the human heart) is used to measure the receiving power. RCS and compare with the computed value at 60 GHz. The receiving power of the Doppler radar can then be calculated from the radar equation at different frequencies. From the theoretical upper bound value of the antenna gain (under the fixed antenna size), by observing the simulated receiving-power comparison, it is found that the Doppler radar can receive more reflected power (from the spherical muscle sphere) for the higher carrier frequency (up to 60 GHz) which may have a better vital-signs sensing performance.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"7 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":"128749179","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}
