Abstract
An antennaless wireless handheld or portable device includes first and second bodies and a hinge mechanically connecting the two bodies. The hinge allows at least one of the two bodies to pivotally move about an axis so that the wireless device can be switched between a closed position in which one of the bodies is substantially arranged on top of the other and an open position in which the first body extends away from the hinge along a first direction and the second body extends away from the hinge along a second direction. A communication module of the wireless device includes a radiating system capable of transmitting and receiving electromagnetic wave signals in a first frequency region and in a second frequency region, wherein the highest frequency of the first frequency region is lower than the lowest frequency of the second frequency region.
