Abstract：The traditional Frequency Selective Surface （FSS） has the problems of high structural profile and low outof-band utof performance.Inthis paper，adesignmethodoffourth-order band-pass frequencyselectivesurface with high rectangularityis proposed.Byusing radiating-guided wave structure，the high-order band-pass frequencyselective filtering characteristics are realized. The frequency selective surface has a very low profile （ 2mm ）and a very high rectangularity （2.8）. Undertheirradiationofelectromagneticwaveswithdifferent incidentangles，itshighrectangularityperformancecanstillbe maintained. Finally，a 10×10 array FSS is designed and fabricated，and its transmission characteristicsare tested and verified. The test results show that the design method is feasible.
