An antenna module for use in a small communications device. The antenna module comprises a dielectric block disposed on a circuit board having a ground plane, an elongated planar strip element folded to fit on different surfaces of the dielectric block, and one or more parasitic element disposed adjacent to the antenna element. In particular, the antenna element is designed to produce resonance frequencies at GSM850 and E-GSM900 bands (the lower bands) and one resonance for the GSM1800/GSM1900/WCDMA2100 bands (the upper bands). The dielectric block can be made of soft or hard plastic.
Module d'antenne utilisé dans un petit dispositif de communication. Le module antenne comporte un bloc diélectrique disposé sur une carte de circuit imprimé ayant un retour de masse, un élément plat de type bande allongé plié pour s'adapter sur différentes surfaces du bloc diélectrique, et un ou plusieurs éléments parasites disposés de manière adjacente à l'élément antenne. Ce dernier est particulièrement conçu pour produire des fréquences de résonance à des niveaux de bandes "les bandes inférieures" GSM850 et E-GSM900 et une résonance pour les bandes "les bandes supérieures" GSM1800/GSM1900/WCDMA2100. Le bloc diélectrique peut être en plastique souple ou dur.
