Abstract :
Plane wave backscattering from two PEC concentric caps is rigorously studied in a wide frequency band. The larger cap is treated as a spherical reflector antenna; the smaller cap is regarded as a back plane placed at the focal region of a reflector antenna. The RCS computations reveal that the structure of two PEC caps is a more efficient reflector than the well-known spherical lens reflector.
