RCS reduction of integrated antenna arrays with resistive sheets

In English Edge diffraction call be a major source of high radar visibility for integrated array antennas. In this paper, it is shown that tapered resistive sheets at the edges of the array can be used to transform the scattering properties of the antenna to that of a metallic plate and hence reduce the radar cross section. Numerical examples of kill array of self-complementary patches and a, bandpass frequency selective radome are presented to illustrate the. results. The RCS reduction is very good for TE polarization but, not IS efficient for the TM polarization.
