The proposed configuration consists of monopole UWB antenna printed on FR-4 low-cost substrate with dimensions of 35 × 35 mm2. The present UWB antenna performs in the frequency spectrum 3.1–10.6 GHz. Through reconfiguration, the antenna has the ability to intelligently manage the problem of the interferences comes from the three narrow bands WiMAX 3.3 – 3.6 GHz, WLAN 5.15 – 5.825 GHz and ITU 8.025 – 8.40 GHz. The reconfiguration is achieved by using three slots inserted into the geometry when there ideal switches is used to control the slots effects. The antenna is designed optimized and simulated using commercial electromagnetic software CST Microwave Studio. The obtained results are good enough where a broad impedance bandwidth is achieved against S11 less than minus 10 dB almost in all the operational states.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"108 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":"129588806","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 fact, it combines a modified version of the IF framework and a self-tuning fusion procedure based on likelihood functions to address issues such as the correlation of the estimates, the transmission shortcomings and the measurement origin uncertainty. The proposed method is evaluated through simulations and the obtained results show that the proposed algorithm performs as well the optimal centralized fusion schema in an idealized environment while it exhibits better robustness capabilities than existing decentralized algorithms when observation origin uncertainty is considered. Moreover, its reduced complexity cost is suitable for real time applications.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"25 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":"114525444","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 a large cross-range target tracking, the classical conversion method becomes inconsistent and is therefore inadequate. In this paper we propose a new decoupled tracking filter that uses Unbiased Converted Measurements within an adaptive αβ filter. The proposed filter, named the Decoupled Unbiased Converted Measurements Adaptive αβ Filter (UCMAαβF), while having a performance similar to that of the Unbiased Converted Measurements Kalman Filter (UCMKF), has the advantage to be simpler to implement for real time applications.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"23 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":"121208043","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 model is used to optimize the antenna array in a record time and calculate the return loss with a sufficient precision. To prove the effectiveness of the suggested BAEM model, a comparison has been achieved between the CST Microwave studio software, Momentum of Agilent, BAEM model and measurements. The comparison of measured and simulated results shows good agreement. The measured results show that a bandwidth from 6.12 to 6.58 GHz is obtained.

By inserting a VIVALDI shape in the Coplanar-Waveguide (CPW) ground plane, the pattern reconfiguration is achieved without changing the original size and form of the monopole. Only two switches were used, thus the main beam is controlled depending on the state of these switches. Therefore, in the band of reconfiguration, the antenna radiates in three different directions (two directive states and one omnidirectional state). Switches were inserted in specific locations so that to eliminate currents to distribute and to radiate from that side, hence the main pattern is shifted in the other side. The proposed approach can be applied to different CPW-Fed monopoles, consequently, it may be suitable for domains were dynamic pattern reconfiguration is needed such as tracking, cognitive radio etc. Our approach is applied to two monopoles: printed stepped rectangular monopole and circular disc antenna. Furthermore, realized prototype and measurements are carried out.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"9 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":"129642234","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}
