Abstract :
The authors analyze the radar cross section of antennas under various load conditions over a wide frequency range. Special emphasis is given to the polarization characteristics of radiated and scattered fields and their influence on the total scattered antenna field. Several techniques for reduction and minimization of antenna scattering are discussed. It is demonstrated how the total scattered field of an antenna can be modified and minimized using appropriate load reflection coefficients. However, in the general case this minimization is only realizable in a narrow frequency range, for certain aspect angles and polarizations.<>
