Abstract

In this paper, a new Yagi-Uda substrate is proposed to obtain radar cross section (RCS) reduction. The Yagi-Uda substrate on which three kinds of metal microstrip lines are etched is put directly on the top of a patch antenna and can reduce RCS sharply by steering the direction of reflecting wave at resonant frequencies. Using a reconfiguration technique, the antenna can radiate without the substrate's effects. When the antenna does not need to work, the Yagi-Uda substrate works to reduce the RCS of the antenna. Besides, the resonant frequencies can be shifted by reconfiguring the Yagi-Uda substrate, so the RCS can be reduced in a broad frequency band.
