In　this　letter,　a　frequency　selective　surface　(FSS)　with　quasi-elliptical　bandpass　filtering　response　and　high-frequency　selectivity　is　proposed.　The　structure　consists　of　two　arrays,　i.e.,　a　hollow　metal　pipe　array　and　a　metal　disk　array　printed　on　a　thin　substrate　layer.　The　FSS　exhibits　a　flat　transmission　in　the　passband　and　fast　roll-off.　By　investigating　the　electric　fields　and　using　equivalent　circuit　models,　physical　insights　into　the　generation　of　the　transmission/reflection　zeros　and　operating　principle　of　the　whole　FSS　are　obtained.　The　positions　of　the　transmission　zeros　can　be　independently　changed　by　adjusting　the　corresponding　parameters　that　tune　the　bandwidth　of　the　passband.　A　prototype　is　fabricated　and　measured　to　verify　the　simulation.
