This configuration allows for size reduction compared to half-wave approaches, while maintaining good sensitivities. The sensing magnitude is the unloaded quality factor, that is more sensitive to glucose changes than the resonant frequency in the 1–10 GHz range. The effects in the sensitivity of a coplanar capacitance placed in the open end are studied by simulations and measurements. The effect of the temperature on the sensitivity is also studied by experimental measurements, and discussion for more accurate sensing is offered.","PeriodicalId":297049,"journal":{"name":"2020 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124954504","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 highly directional antennas with beam scanning ($boldsymbol{20^{mathrm{o}}}$) capabilities have been designed and employed for breathing rate (BR) and heartbeat rate (HR) detection of a person located up to 3m radial distance from the micro–DR at various angular positions. The 60GHz-band RVSM results showed high detection sensitivity, especially for incredibly small HR signal, due to the shorter operating wavelength at 60GHz-band. The proposed beam scanning micro–DR offers flexibility for the subject to change their position within $boldsymbol{20^{mathrm{o}}}$ angular space while remaining under continuous health monitoring.","PeriodicalId":297049,"journal":{"name":"2020 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128906524","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}

State-of-the-art implanted medical devices mostly operate with On-Off Keying (OOK) which is the simplest type of modulation. However, MATLAB simulations depict the higher power efficiency of Binary Phase-Shift Keying (BPSK) over OOK and other binary modulation techniques. Moreover, at equal Bit Error Rate (BER) and emitted signal power, the higher power efficiency eventually results in a gain of achievable depth that is quantified in a gelatin phantom. At last, alternatives to power-hungry Phased-Locked Loop (PLL)-based demodulation circuits are explored as their complex structure generally thwarts the use of BPSK modulation.","PeriodicalId":297049,"journal":{"name":"2020 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127538610","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}
