Abstract:
1. A wireless handheld or portable device, comprising: a first body; a second body; a hinge mechanically connecting the first and second bodies, the hinge allowing at least one of the first and second bodies to pivotally move about an axis such that the wireless device is switchable between a closed position in which one of the first and second bodies is substantially arranged on top of the other of the first and second bodies 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 different from the first direction; and a communication module including 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; wherein the radiating system comprises a radiating structure comprising: wherein, when the wireless device is in the closed position, the input impedance of the radiating structure at each of the at least one internal port when disconnected from the radiofrequency system has an imaginary part not equal to zero for any frequency of the first frequency region; and wherein said radiofrequency system modifies the impedance of the radiating structure, providing impedance matching to the radiating system in the at least two frequency regions of operation of the radiating system both when the wireless device is in the closed position and in the open position.
