Abstract
A tunable high impedance surface device () includes a conductive ground plane () and a plurality of conductive elements (-) electrically connected to the conductive ground plane (). The device () also includes a plurality of capacitive elements (-) operable to vary a predetermined electromagnetic characteristic of the apparatus and standoffs () between the plurality of capacitive elements (-) and the plurality of conductive elements (-). In one form, laser-drilled and electrically conductive micro-vias () extend through the standoffs () thereby electrically connecting the plurality of capacitive elements (-) to a data bus (). The capacitive elements (-) may be integral with a circuit board () that supports the plurality conductive elements (-). Either the capacitive elements (-) or the conductive elements (-) are mechanically flexible and selectively movable to controllably adjust the distance () between the capacitive and conductive elements.
