ABSTRACT:
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.
