It consists of a metal plate whose length has been optimized to work at a frequency of 915MHz and to which a second plate charged with a capacitor of 0.8pF has been added to create a second resonance at the frequency of 868MHz. The dimensions and positions of the short-circuit and the feeding strip of the PIFA have been optimized to maximize the radiation efficiency of the antenna. A good impedance matching and high radiation efficiency were obtained in both 868 and 915 MHz frequency bands.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"59 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":"131608079","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}

It aims at providing a flexi- ble balancing between throughput and fairness maximization and incorporates unequal power repartition among allocated subbands using waterfilling. Its main strength is the ability to achieve a high level of fairness in every scheduling slot, therefore improving the quality of experience for all users. Simulation results show that the proposed metric enhances fairness and improves system capacity, when compared to the conventional proportional fairness scheduler.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"2 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":"127842267","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, we consider three types of blood vessels with different sizes. We investigate the impact of the number of blood vessels and their alignment on the transmission of microwave signals through the fat channel. In our study, we employ two probes that act as a transmitter and a receiver. The probes are designed to operate at the Industrial, Scientific, and Medical radio band (2.45 GHz). For a channel length of 100 mm, our results indicate that the presence of the blood vessels may increase the channel path loss by $tilde1.5$ dB and $tilde4.5$ dB when the vessels are aligned and orthogonally aligned with the fat channel, respectively.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"114 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":"114592376","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 goal of this study is to achieve precise bearing detection in an indoor Rician fading channel using the PRW method in conjunction with the mean IQ-value (MIQ) method that extracts angle information in random multipath scattered fields. Monte-Carlo simulation-based analytical results show that by using the PRW method in conjunction with the MIQ method, the AOA antenna with a half of the number of elements, compared with our previously studied counterparts, provides an estimated angle error of less than 7°, even in the case of a severe Rician fading channel with an extremely small line-of-sight (LOS) stationary component where the rice factor or K-factor is −10dB.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"44 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":"124782018","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 problem is solved by the use of two active RX-TX antennas which are connected one with other with the feeder of needed length. The first antenna is installed at the building rooftop or at any other dominant altitude; the second antenna is installed in a shielded room (underground garage, tunnel etc). The design of each antenna is based on the use of one-port resonant transistor amplifier with the opened resonant system. Resonant system is realized on microstrip patch antenna. The antenna operation assumes the implementation of receiving and transmitting modes simultaneously. The switching between receiving and transmitting modes does not need to be implemented.
