Abstract

Radar cross section (RCS) of ground planes can be reduced along the principal planes by utilizing electromagnetic bandgap (EBG) structures. Checkerboard surfaces, combining two different EBG structures each on a quadrant of the same ground plane, can realize a wide frequency bandwidth for the 10-dB RCS reduction, because the scattered fields from checkerboard surfaces are redirected toward four quadrants. This communication proposes dual-frequency band checkerboard surfaces with 10-dB RCS reduction bandwidths of 61% and 24% by utilizing two dual-band EBG structures, while the surfaces maintain scattering in four quadrants. Bistatic and monostatic RCS of dualband checkerboard surfaces are simulated and the results are compared to the RCS of the corresponding perfect electric conductor (PEC) surface. Comparison of the monostatic RCS between the measurements and simulations, as a function of frequency, is considered for both TEz and TMz polarizations. A very good agreement is obtained between measurements and simulations.
