An antenna array includes a plurality of antenna unit cells, a ground plane, and at least one artificial magnetic layer AML unit cell. At least one AML unit cell is disposed between at least two adjacent ones of the antenna unit cells. The AML unit cells include a pair of split ring resonators through a ring dielectric layer, and the resonators are capacitively coupled to the a ground plane of the antenna array through a capacitor dielectric layer. The resonators are orthogonal to one another and to the ground plane, and more than one pair may be defined in each AML unit cell. Magnetic energy from the antenna unit cells induces an electric field in the resonators, and the resulting magnetic field is strongly coupled to the AML unit cell to inhibit mutual coupling between radiating elements by suppression of surface wave propagation. |
