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

Figure 1

Structure of the dipole array on the HIS ground plane. The top figure gives a view of a unit cell of the infinite phased dipole array printed on the HIS ground plane. The bottom figure shows 4-by-4 unit cells of the HIS ground plane. Some key parameters are as follows: the square patch size , the gap between patches , the via size , the dipole size (length) and (width), the substrate thickness and , the lattice constant is , and the substrate permittivity and .
