Planar　frequency　selective　fabrics　(FSFs)　with　Jerusalem-shaped　units　were　proposed　in　this　paper.　In　accordance　with　the　previous　work,　the　design　process　was　specifically　for　10GHz.　Through　simulation　and　optimization　procedures,　the　ideal　structure　parameters　were　obtained,　and　the　proposed　FSFs　with　optimized　parameters　showed　good　stability　to　differential　and　integral　algorithms,　transmission　modes　and　incidence　angles　of　electromagnetic　(EM)　waves.　To　further　explore　the　internal　EM　transmission　mechanism　of　FSFs,　the　surface　currents　at　4,　10　and　14GHz　were　analyzed　comparatively.　Based　on　the　simulated　results,　10　samples　with　the　polyester　fabric　substrate　were　fabricated　through　the　computer-based　carving　method　and　the　transmission　characteristics　were　tested　using　the　Shielding　Room　Method.　The　fabricated　FSFs　indeed　showed　good　frequency　response　characteristics,　as　expected,　and　the　comparison　of　measured　and　simulated　results　verified　the　validity　of　the　design　procedures.　The　influence　rules　of　structure　parameters　(p,　a,　b,　c)　were　further　studied　in　detail　by　changing　their　values　properly,　and　the　simplified　equivalent　circuit　model　was　proposed　to　explore　the　corresponding　physical　mechanism,　which　could　provide　physical　insight　into　the　performance　of　the　FSFs.
