A high impedance surface () has a printed circuit board () with a first surface () and a second surface (), and a continuous electrically conductive plate () disposed on the second surface () of the printed circuit board (). A plurality of electrically conductive plates () is disposed on the first surface () of the printed circuit board (), while a plurality of elements are also provided. Each element comprises at least one of (1) at least one multi-layer inductor () electrically coupled between at least two of the electrically conductive plates () and embedded within the printed circuit board (), and (2) at least one capacitor () electrically coupled between at least two of the electrically conductive plates (). The capacitor () comprises at least one of (a) a dielectric material () disposed between adjacent electrically conductive plates, wherein the dielectric material () has a relative dielectric constant greater than 6, and (b) a mezzanine capacitor embedded within the printed circuit board ().
