1. Method for fabricating an antenna structure having adjustable radiation characteristics, the method comprising the steps of comprising:

  • providing a frequency selective surface including a patterned layer of conducting material having electromagnetic properties that vary as a function of frequency;

    positioning an antenna element proximate to the frequency selective surface to promote near field coupling of electromagnetic energy between the antenna element and the patterned layer of conducting material, when the antenna element is operated at a selected frequency; and

    structuring the patterned layer of conducting material to have specific electromagnetic properties at the selected frequency of operation of the antenna element to obtain a predetermined adjustment of the radiation characteristics of the antenna structure.
