This invention enables Frequency Selective Surface (“FSS”) and Artificial Magnetic Conductor (“AMC”) which exhibits Electromagnetic Band Gap (“EBG”) in any of the substrate's layer from a small and thin systems and sub-systems in package to a large-format PCBs. The metamaterial substrate may be integrated with electronic circuit components or buried in PCBs for circuit designs capable of transmitting, receiving and reflecting electromagnetic energy, altering electromagnetic properties of natural circuit materials, enhancing electrical characteristics of ...
1. An apparatus comprising a substantially small sized and thinner electromagnetic band gap structure for a predetermined band gap frequency band, said apparatus comprising: a. coplanar conductive unit elements that are periodically arrayed with an edge to edge spacing d between each of the adjacent said coplanar conductive unit elements forming a first layer,b. a dielectric having a thickness hr and a relative dielectric permittivity ∈r forming a second layer,c. a contiguous conductive plane forming a third layer,d. a capacitive surface means arranged i...
