Description

Antennes planaires et techniques de miniaturisation by Farouk Chetouah Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Dans ce livre, afin de miniaturiser les antennes planaires; nous avons utilisé les techniques suivantes: la première technique consiste à charger une antenne à résonateur diélectrique rectangulaire (ARDR) par un matériau BST à très forte permittivité diélectrique dont nous nous sommes intéressés par la modélisation et l'analyse électromagnétique de l'antenne avant et après l'empilement par ce matériau. L'antenne proposée fonctionne autour de 2,31 GHz et fournit une bande passante d'impédance de 20 MHz. La deuxième technique de miniaturisation utilisée est la structure à défaut dans le plan de masse (DGS), où la fabrication des deux antennes microrubans a été réalisée; la première antenne est à bande passante étroite (272 MHz), tandis que la deuxième qui a une surface de patch plus petite et une taille globale de 10 × 6 mm² présente une bande passante large (supérieure de 1 GHz). Afin de valider les résultats numériques, des mesures ont été effectuées. Ces résultats ont été satisfaisants. Les trois projets discutés montrent clairement l'importance de ces deux techniques dans la miniaturisation des antennes planaires.

  1. Like new condition, safe packaging, good communication from seller. Fair price for the quality. Shipping was on time, but tracking information took over a week to receive. The book was as-described with minor cosmetic flaws (indentations in some pages, for example). I wish the listings showed the actual item being sold to you instead of just an accurate stock photo. This edition and appearance of George Orwell's 1984 here is a nice pocket-sized hardcover. I would buy from this shop again.

  2. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.

  3. Lightning fast shipping. Item arrived before the delivery date, perfect. Item arrived carefully packaged and was exactly as described. Very pleased.  Great communication throughout the process. Very attentive to detail and responsive. Will buy from again!  Had a small issue with the item, but the seller resolved it quickly. Great customer service!  The seller went above and beyond to make sure I was happy with my purchase. Highly recommended!
