Abstract:
A method for stabilizing the electrical impedance of a structure including a pair of parallel planar conductors separated by a dielectric layer and thereby reducing an amount of electromagnetic energy radiated from the structure, the method comprising:selecting a spacing distance dependent upon a relative dielectric constant of the dielectric layer;generating a grid comprising two orthogonal sets of parallel lines, wherein the parallel lines of each set are separated by the spacing distance, and wherein the grid has physical dimensions greater than or equal to corresponding dimensions of the structure such that the grid completely covers the structure when overlayed upon the structure;estimating a characteristic impedance of the structure dependent upon at least one physical dimension of the grid; andelectrically coupling an electrical resistance between the planar conductors, wherein the electrical resistance has a value dependent upon the characteristic impedance of the structure.
