Claim 2:
3. The antenna apparatus of claim 1, wherein the first resonant layer comprises a plurality of first resonant units arranged at regular intervals, the second resonant layer comprises a plurality of second resonant units arranged at regular intervals, each of the plurality of first resonant units is a conductive patch, each of the plurality of second resonant units is a conductive patch and defines a hollow structure penetrating through two opposite surfaces of each of the plurality of second resonant units, each of the plurality of first resonant units has a side length of L1, each of the plurality of second resonant units has a side length of L2, wherein P>L1≥L2, P is an arrangement interval of the plurality of first resonant units and the plurality of second resonant units, and a larger area of the hollow structure leads to a greater difference between L1 and L2.
