A high impedance surface having a reflection phase of zero in multiple frequency bands and a method of making same. The high impedance surface includes a ground plane; a plurality of conductive plates disposed in a first array spaced a distance from the ground plane, the distance being less than a wavelength of the radio frequency beam, said first array having a first lattice constant; and a plurality of conductive elements associated with said plurality of conductive plates, said plurality of conductive elements defining a second array, said second array having a lattice constant greater than the lattice constant of the first array.
