Abstract
A switchable artificial magnetic conductor (S-AMC) element that includes a conductive layer, a conductive patch located on one side of the conductive layer and electrically isolated from the conductive layer, and an open stub located on an opposite side of the conductive layer and electrically isolated from the conductive layer. A switch element is configured to selectively open and close an electrical connection between the conductive patch and the open stub in response to a control signal. When the electrical connection is closed the conductive patch presents a high impedance, magnetically conductive surface for radio frequency (RF) signals within a defined frequency band, and when the electrical connection is open the conductive patch presents an electrically conductive surface for RF signals within the defined frequency band.
