1. A multi-band antenna system, comprising:
a plurality of radiating element arrays;
a plurality of feeding networks separately corresponding to the plurality of radiating element arrays;
a frequency selective surface (FSS); and
a reflection panel, wherein:
the plurality of radiating element arrays are located above the reflection panel when the reflection panel is horizontally placed, and all or some of the plurality of radiating element arrays are stacked forming stacked radiating element arrays;
the FSS is located between the stacked radiating element arrays; and
a feeding network corresponding to at least one radiating element array in the stacked radiating element arrays is electrically connected to the FSS according to an electrical connection manner, wherein the electrical connection manner is a direct current connection manner or a segmented direct current connection manner, or the feeding network corresponding to the at least one radiating element array is integrated on the FSS.
