This book was released on 2009 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: La bande de fréquence millimétrique autour de 60 GHz est considérée comme l’une des meilleures options pour l’implémentation des réseaux sans fils à très hauts débits de type WPAN (wireless personal area network). De plus, les systèmes multi-antennes de type MIMO (multiple-input multiple-output) sont très prometteurs. Ils peuvent augmenter de manière significative l’efficacité spectrale ou la fiabilité des communications sans fil. De ce fait, l’utilisation de systèmes multi-antennes à 60 GHz est, théoriquement, très prometteuse. Bien que les performances des systèmes MIMO aient été étudiées de manière approfondie à la fois théoriquement et expérimentalement à basses fréquences (2 et 5 GHz), il y a clairement un manque d’évaluation expérimentale de ces systèmes à 60 GHz. De plus, la conception et l’évaluation d’antennes millimétriques compactes à bas coûts pour des applications de type WPAN sont des sujets sur lesquels beaucoup de recherches doivent être encore faites. Dans la première partie de la thèse, le premier sondeur de canal MIMO à 60 GHz est présenté. Ce système, construit à partir d’un sondeur existant pour 2 et 5 GHz, utilise des réseaux d’antennes virtuelles. Afin d’améliorer la résolution temporelle, deux autres systèmes de mesure ont été développés. Le premier est construit à partir d’un sondeur ultra large bande et le second à partir d’un analyseur vectoriel de réseau. Ces systèmes permettent la caractérisation totale du canal MIMO dans les domaines temporel et angulaire. Dans la seconde partie, les performances de techniques pour systèmes multi-antennes sont analysées grâce aux mesures obtenues dans la première partie de la thèse. Les trois techniques étudiées sont: MIMO, MIMO avec sélection d’antennes et dépointage de faisceau. Les résultats indiquent que la capacité du canal MIMO mesuré est relativement proche de celle d’un canal idéal. Dans des conditions réalistes, la capacité obtenue grâce à la technique MIMO avec sélection d’antennes est souvent inférieure à celle obtenue avec la technique MIMO. Par ailleurs, lorsque l’on considère un réseau à déphasage avec des pertes réalistes, il apparait que la capacité obtenue avec la technique MIMO est presque toujours supérieure à celle obtenue avec la technique du dépointage du faisceau. Dans la dernière partie de la thèse, une antenne omnidirectionnelle est présentée. Cette antenne convient parfaitement aux applications de types WPAN car elle est plane et n’utilise qu’une seule couche de métallisation, ce qui la rend facile à réaliser et peut coûteuse. De plus, un banc de mesure quasi-3D de diagrammes de rayonnement d’antennes à 60 GHz à été développé. Ce système a une très bonne répétabilité. Le rayonnement de la pointe elle-même a été mesuré et les résultats indiquent que c’est la principale limitation de la dynamique d’amplitude de ce système.

Book excerpt: This book highlights technology trends and challenges that trace the evolution of antenna design, starting from 3rd generation phones and moving towards the latest release of LTE-A. The authors explore how the simple monopole and whip antenna from the GSM years have evolved towards what we have today, an antenna design that is compact, multi-band in nature and caters to multiple elements on the same patch to provide high throughput connectivity. The scope of the book targets a broad range of subjects, including the microstrip antenna, PIFA antenna, and the monopole antenna to be used for different applications over three different mobile generations. Beyond that, the authors take a step into the future and look at antenna requirements for 5G communications, which already has the 5G drive in place with prominent scenarios and use-cases emerging. They examine these, and put in place the challenges that lie ahead for antenna design, particularly in mm-Wave design. The book provides a reference for practicing engineers and under/post graduate students working in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Software radio ideally provides the opportunity to communicate with any radio communication standard by modifying only the software, without any modification to hardware components. However, taking into account the static behavior of current communications protocols, the spectrum efficiency optimization, and flexibility, the radio domain has become an important factor. From this thinking appeared the cognitive radio paradigm. This evolution is today inescapable in the modern radio communication world. It provides an autonomous behavior to the equipment and therefore the adaptation of communication parameters to better match their needs. This collective work provides engineers, researchers and radio designers with the necessary information from mathematical analysis and hardware architectures to design methodology and tools, running platforms and standardization in order to understand this new cognitive radio domain.
