Claim:
1. A method for determining a preferred range of thickness for an insulator layer formed between an antenna structure and a metal layer comprising the steps of: forming said insulator layer between said antenna structure and said metal layer, with said insulator layer being in direct contact with said antenna structure and said metal layer; where said insulator layer exhibits capacitance coupling the antenna structure and the metal layer; and wherein the thickness of the insulator layer affects the value of the capacitance between said antenna structure and said metal layer; varying the thickness of the insulator layer over a range extending between a first, minimum, value and a second, higher, value for varying the capacitance exhibited between said antenna structure and said metal layer; transmitting RF signals to the combination of the antenna structure, the insulator layer and the metal layer for selected values of insulator thickness within said range; sensing the amplitude of the signals received at the antenna structure for said selected values of thickness of the insulator layer; and identifying the insulator thickness which results in the highest amplitude of signal being received at the antenna structure.
