A frequency selective surface which can provide up to 4 passbands will be proposed. The passbands are nearly independent so it simplifies the design procedure. The base of the design is according to frequency reuse in cellular communications which there are N different frequencies in one cluster. The array cells in this FSS are hexagons and the resonators on top and bottom of each cell are aperture loops. As the elements and cells are in the most geometrical symmetry, stability about polarization and angle of incidence is in the good state. As some examples, a dual-band, a triple-band and a quad-band FSS are simulated with CST software. The results are in good agreement with theoretical calculations.
