1. An antenna for radiating an electromagnetic field having both linear and circular polarization, said antenna comprising:

  • a ground plane;

    a dielectric layer disposed on said ground plane and having at least one exposed surface that radiates the electromagnetic field; and

    a first feeding element disposed on said at least one exposed surface for electrically exciting said dielectric layer to provide the linear polarization at a first frequency having a first effective wavelength; and

    a second feeding element disposed on said at least one exposed surface for electrically exciting said dielectric layer to provide the circular polarization at a second frequency having a second effective wavelength;

    whereinsaid feeding elements are separated by a distance greater than ⅛

    wavelength of any of the effective wavelengths.
