The utility model discloses a frequency selection surface structure based on multilayer annular gap patches. The structure is formed by N*M resonance units. Each resonance unit comprises two layers of medium substrates which are placed in parallel. Upper and lower surfaces of each layer of medium substrate are provided with one layer of annular gap patch respectively. The structure of each annular gap patch is characterized in that center points of four edges of an inner ring of a FSS annular patch are provided with rectangular gaps respectively; the rectangular gaps are symmetrical about the center points of the inner ring edges. The four layers of annular gap patches are adopted so that cascade of a multistage band-stop filter is realized; band-stop performance is superior and a bandwidth is wide.
