However, short-range localization of passive moving objects in indoor environments remains a technical challenge. In this paper, we propose a single-frequency continuous-wave Doppler radar sensor implemented in a form of a single-input multiple-output (SIMO) architecture with a redundant receiving channel. It only uses the Doppler information in the localization. In this case, this localization is naturally immune to stationary clutters such as walls and furniture, making it only responsive to moving objects. The obtained results imply the potential for the localization and tracking of moving objects in indoor environments with strong stationary scatters.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128619603","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 applied IC was fabricated in a 130 nm SiGe process featuring an ft and fmax of 240 GHz and 330 GHz. The on-chip system contains a 120 GHz VCO with a tuning range of 7 GHz featuring a divide-by-64 circuit to enable external PLL operation. An important feature of the IC is high-precision and high-resolution phase shifting based on a slow-wave transmission lines approach with digital control. This allows for direct digital readout ability. The on chip power detector provides DC output signals giving the opportunity to record transfer functions of the interferometer. It enables sample emulation capability by phase shift inducement in the measurement as well as a reference transmission line. The motherboard of the system provides PLL stabilization for frequency sweeps. The proposed approach is capable of automated dielectric monitoring by phase compensation.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131061980","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}

Current saturation becomes a limiting factor for ultrafast waveforms when the diffusion current through the capacitive depletion region exceeds the current carrying capacity of the unde-pleted resistive region.

A spinning magnet array's propagation characteristics for Ultra Low Frequency (ULF) communication have been presented and experimentally demonstrated. If low data rates are acceptable, ULF is an attractive choice for RF denied environments such as underwater and underground. ULF antennas, if made portable within a diameter of 1m, will operate under an electrical length of the order of 10−4 to 10−6 wavelengths in free space. Like for any other electrically small antenna, Chu's limit kicks in and defines the lower bound of the radiation quality factor. We have proven that the proposed Spinning Magnet Array breaks Chu's limit and has the potential to operate at improved bandwidth using Direct Antenna Modulation (DAM).","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134309412","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 technique relies on the near-field coupling between loop antennas. The antennas are realized with conventional aluminum bond wires of 17 μm in diameter. The loop planes are orthogonal to the chip surface and welded on ad-hoc pads. An integrated transmission line is used to close the loop, with one side of the loop attached to the source or load impedance, and the other connected to ground. This technique demonstrated a minimum insertion-loss of 4.5 dB over a frequency band of operation spanning from 178 GHz to 204 GHz.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133894746","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}

To improve the input sensitivity, a power matching network is included at the injection terminal of the switch transistor. In addition, to enhance the frequency locking range, body bias technique (i.e. a body resistor in conjunction with a zero body-source bias) is adopted in the switch transistor to reduce its threshold voltage. The result shows that a wide locking-range of 23.5 GHz (28.9%) was achieved.
