Abstract
A high-frequency Electromagnetic Bandgap (EBG) device, and a method for making the device are provided. The device includes a first substrate including multiple conducting vias forming a periodic lattice. The vias of the first substrate extend from the lower surface of the first substrate to the upper surface of the first substrate. The device also includes a second substrate having multiple conducting vias forming a periodic lattice. The vias of the second substrate extend from the lower surface of the second substrate to the upper surface of the second substrate. The second substrate is positioned adjacent to, and overlapping, the first substrate, such that the lower surface of the second substrate is in contact with the upper surface of the first substrate, and such that a plurality of vias of the second substrate are in contact with a corresponding plurality of vias of the first substrate.
