In this paper we present a comparison of two methods for radar cross section reduction (RCSR) of a wing-front profile. The aim is to reduce RCS over the frequency range 1-16 GHz in a forward sector of the traveling direction. We achieved a 5 dB reduction of the two dimensional monostatic radar cross section (RCS) for 68% (or more) of the frequency band for the polarization with the electric field parallel to wing surface (TM2). It is shown that the Jaumann screen has a better RCSR performance than a shape optimized screen in the present case. The total thickness of the Jaumann screen is only 4.5 mm. The 5 dB 2D-RCSR frequency range for the orthogonal polarization in which the electric field is orthogonal to axis of periodicity (TEz) is over 43% of frequency band.
