Abstract
A reduced radar cross section (RCS) antenna does not require housing the antennas in a radar-mitigating radome. Elements of the antenna are made from, or include, frequency selective surfaces that reduce reflection of radar or other signals. In some embodiments, the frequency selective surfaces are electrically tunable, thereby enabling a user or system to dynamically adjust the frequency or frequencies that are mitigated.
