1. A multi-band strip antenna for a communication device, the antenna comprising:

  • a three-dimensional rectilinear antenna substrate having a plurality of faces; and

    a radiation element formed of a plurality of N, elongated planar conductive segments, each of which is disposed upon at least one face of the three-dimensional rectilinear antenna substrate such that the segments are electrically connected to each other in series, the combined lengths of the segments being selected to be substantially equal to a one-quarter wavelength a lowest frequency band of two different frequency bands in which the strip antenna is capable of operating.
