Abstract
An electromagnetic band gap checkerboard surface including a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant. The first and third quadrants each include a multiplicity of first dual-band electromagnetic band gap structures having a first resonant frequency and a second resonant frequency. The second and fourth quadrants each include a multiplicity of second dual-band electromagnetic band gap structure having a third resonant frequency and a fourth resonant frequency. The first quadrant is directly adjacent to the second quadrant and the fourth quadrant; the third quadrant is directly adjacent to the second quadrant and the fourth quadrant; the first quadrant and the third quadrant are diagonally juxtaposed; and the second quadrant and the fourth quadrant are diagonally juxtaposed.
