Download or read book Conception, caractérisation et réalisation de réseaux d’antennes «fil-plaque» written by Hongjiang Zhang and published by . This book was released on 2011 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce mémoire s’inscrit dans le cadre du développement des communications terrestres avec les véhicules mobiles. Dans ce domaine en plein expansion, nous avons conçu les antennes à intégrer sur le toit du train de manière à optimiser la communication WIMAX avec les stations de base pour le projet THDT (Très Hauts Débits dans les Trains) en partenariat avec la région du Limousin et d’autres partenaires industriels. Le but de ce projet est de fournir du très haut débit dans les trains de la région en utilisant une liaison de type WiMAX mobile entre la station de base et le train. Les antennes proposées sont les réseaux d’antennes fil-plaques à fort gain. Elles répondent aux cahiers des charges particuliers que nous avons élaborées à partir des études sur le bilan de liaison et les contraintes d’environnement du train.

This book was released on 2004 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce mémoire s’inscrit dans le cadre du développement des réseaux de télécommunication sans fil terrestres. Dans ce domaine en pleine expansion, les antennes pour stations de base ont pour objectif la couverture des cellules la plus étendue et la plus homogène possible. Après un état de l’art des systèmes existants et des problèmes rencontrés, l’étude et la conception de deux types d’antennes ont été réalisées : - une antenne dite en « cosécante carrée » permettant de répartir l’énergie émise de manière homogène dans toute la cellule. Cette antenne a été réalisée en technologie imprimée pour le système LMDS (Local Multipoint Distribution Service) à 40 GHz. - une antenne à Bande Interdite Electromagnétique (BIE) présentant un diagramme omnidirectionnel en azimut et un fort gain. La conception de ce nouveau type d’antenne, appelé antenne BIE coaxiale, a nécessité une étude théorique puis paramétrique. Une réalisation a été présentée à 5 GHz

Book Synopsis Microwave and RF Design of Wireless Systems by : David M. Pozar
Download or read book Microwave and RF Design of Wireless Systems written by David M. Pozar and published by John Wiley & Sons. This book was released on 2000-11-29 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: David Pozar, author of Microwave Engineering, Second Edition, has written a new text that introduces students to the field of wireless communications. This text offers a quantitative and, design-oriented presentation of the analog RF aspects of modern wireless telecommunications and data transmission systems from the antenna to the baseband level. Other topics include noise, intermodulation, dynamic range, system aspects of antennas and filter design. This unique text takes an integrated approach to topics usually offered in a variety of separate courses on topics such as antennas and proagation, microwave systems and circuits, and communication systems. This approach allows for a complete presentation of wireless telecommunications systems designs. The author's goal with this text is for the student to be able to analyze a complete radio system from the transmitter through the receiver front-end, and quantitatively evaluate factors. Suitable for a one-semester course, at the senior or first year graduate level. Note certain sections have been denoted as advanced topics, suitable for graduate level courses.
Download or read book 1914 written by Jean Echenoz and published by New Press, The. This book was released on 2014-01-07 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five Frenchmen go off to war, two of them leaving behind a certain young woman who longs for their return. But the main character in 1914 is the Great War itself. Jean Echenoz, the multi–;award–;winning French literary magician whose work has been compared to Joseph Conrad and Lawrence Sterne, has brought that deathtrap back to life, leading us gently from a balmy summer day deep into the insatiable—and still unthinkable—carnage of trench warfare. With the delicacy of a miniaturist and with irony both witty and clear–;eyed, the author offers us an intimate epic with the atmosphere of a classic movie: in the panorama of a clear blue sky, a biplane spirals suddenly into the ground; a tardy piece of shrapnel shears the top off a man's head as if it were a soft–;boiled egg; we dawdle dreamily in a spring–;scented clearing with a lonely shell–;shocked soldier strolling innocently to a firing squad ready to shoot him for desertion. But ultimately, the grace notes of humanity in 1914 rise above the terrors of war in this beautifully crafted tale that Echenoz tells with discretion, precision, and love.

Download or read book I'm Gone written by Jean Echenoz and published by New Press, The. This book was released on 2014-05-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of France's prestigious Prix Goncourt and a runaway bestseller, Jean Echenoz's I'm Gone is the ideal introduction to the sly wit, unique voice, and colorful imagination of “the master magician of the contemporary French novel” (The Washington Post). Nothing less than a heist caper, an Arctic adventure story, a biting satire of the art world, and a meditation on love and lust and middle age all rolled into one fast-paced, unpredictable, and deliriously entertaining novel, I'm Gone tells the story of an urbane art and antiques dealer who abandons his wife and career to pursue a memorably pathetic international crime spree. “Crisp and erudite” (The Wall Street Journal), “seductive and delicately ironic” (The Economist), and with an unexpected sting in its tail, I'm Gone—translated by Mark Polizzotti—is a dazzling, postmodern subversion of narrative conventions and an amused look at the absurdities of modern life. With a wink and a nod and a keen eye for the droll detail, Echenoz invites the reader “to enjoy I'm Gone in the same devil-may-care spirit in which it is offered” (The Boston Sunday Globe).
