1. A dielectric resonator antenna system comprising:

  • a dielectric substrate sheet having opposite first and second surfaces;

    a patch of electrically conducting material having a center frequency formed on said first surface, the patch having a length that varies across the width of the patch;

    a ground plane formed on said second surface;

    means for feeding signals to and from the patch; and

    a dielectric resonating element, adjacent to said first surface and said patch, said resonating element having a dielectric constant, a thickness and a size, wherein said dielectric constant, said thickness and said size of said dielectric resonating element comprises a means for resonating at frequencies including said center frequency, said substrate, patch and resonating element comprising a stack.
