A Study of a Wide-Angle Scanning Phased Array Based on a High-Impedance Surface Ground Plane

Figure 10

Dispersion curves of the grounded HIS substrate, where the blue and the red solid lines are the first two SW modes of the HIS; the red dashed line is the LW mode supported by the structure composed of the HIS and the dipole array. The inset is a schematic of a unit cell of the HIS substrate.
