The data reported in this work reveal the significance of impulsive noise in indoor locations. The received impulsive noise peak levels are significant, 30 dB higher than the background noise level in most cases. The procedure and methodology of measurements and the characterization of the impulsive noise have been made according to the ITU-R Recommendation SM.1753. This report contributes to the ITU-R Question 214-5/3, which asks for more radio noise studies.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122841510","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 validate this system, measurements have been done with two trihedral corner reflectors lying on a grass field, using our system and a VNA. We have processed the acquired data using the Back Projection Algorithm (BPA). VNA and MIMO-MCR give similar results with a vertical resolution of 0.37 m@1.6 m ground range and a vertical ambiguity of 0.74 m@1.6 m ground range. Therefore, the system is fully operational.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123902355","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 the case of active radio- frequency quantum sensors, however, there exist several practical challenges, the most significant of which is the fast and efficient generation of a large number of entangled microwave photons. In a previous paper we proposed a method, called virtual modes, for mitigating this limitation by using a distributed architecture of quantum sensor units to synthetically increase the effective number of distinguishable modes available for target detection. Although this architecture was shown to incur an increase in noise cross-contamination, we showed that judicious sensor configurations can mitigate this effect. In this paper we examine more sophisticated cross-noise statistical models that permit the number and spatial distribution of sensors to be optimized to further reduce the net detection error probability of the proposed approach.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128423710","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 the L-band the use of highly directive antennas such as horn antennas is restricted by the size they would have. We propose therefore to use a pair of log-periodic arrays instead although they are less directive and supposed to exhibit a stronger mutual coupling. A differential technique based on subtracting the impulse response with and without target is also proposed. The method was successfully validated on a rectangular target.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128455262","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 techniques are employed in the multiband antenna design. The first combines multiple off-center-dipoles to achieve multiband characteristics. The off-center-fed-dipole technique facilitates the adjustment of impedance matching. The second technique employs trapezoidal elements to lower the antenna height and expand the frequency bandwidth by increasing the current pathways. Using these techniques we propose four antennas and one of these achieves operation in multiple bands including the 700 to 900 MHz bands and the 1.7 GHz to 2 GHz bands. The proposed antennas are suitable for M2M applications due to their multiband frequency characteristics and low profiles.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126429610","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}
