1. An apparatus comprising:

  • a portable communication device;

    at least a first single antenna, the first single antenna being included entirely within the portable communication device;

    said first single antenna having a surface that radiates and receives electromagnetic waves, an entirety of an edge enclosing the surface shaped as a substantially non-periodic curve;

    said substantially non-periodic curve comprises a multiplicity of connected segments, each segment is shorter than one tenth of at least one operating free-space wavelength of the antenna;

    the first single antenna radiates at multiple different operating Wavelengths with at least one of the operating wavelengths corresponding to an operating wavelength of a cellular telephone system;

    the first single antenna radiates across each of at least two non-overlapping cellular telephone system frequency bands; and

    the first single antenna simultaneously receives electromagnetic waves corresponding to at least two non-overlapping cellular telephone system frequency bands.
