About the Book

Aujourd'hui, l'industrie cellulaire a besoin de systèmes d'antennes capables de fonctionner sur de nombreuses sous-bandes souhaitées dans la gamme de fréquences allant du LTE aux fréquences Wi-Max. De nombreuses antennes ont été mises en oeuvre pour couvrir l'ensemble de la bande allant de 700 MHz à 6 GHz avec des caractéristiques électriques suffisamment bonnes; cependant, ces antennes couvrent malheureusement certaines fréquences qui ne sont pas utilisées et sont sans intérêt. Cela se fait au prix d'une augmentation de la taille de l'antenne conçue, ce qui la rend peu commode et peu pratique pour les applications considérées. Le but de ce travail est de concevoir un système d'antenne patch unique capable de résonner aux sous-bandes désirées avec des caractéristiques directionnelles suffisamment bonnes (dépassant 3 dB dans la gamme de fréquences) et avec une taille ne dépassant pas (7 x 7 x 1) cm3. Par rapport à d'autres antennes à large bande destinées au même usage, les fentes fractales génèrent des résonances multiples dans les sous-bandes souhaitées sans augmenter la taille du patch. La manipulation des dimensions, positions et formes fractales nous permet de sélectionner le point de résonance ainsi que l'efficacité du système d'antenne.
