| Zusammenfassung: | In this letter a broadband spatial band‐stop filter using Sierpinski space‐filling geometry (SSG) operating at Korean personal communication service (PCS) frequency band (1.75–1.87 GHz) is presented. A single layer frequency selective surface (FSS) consisting of SSG of iteration Level 4 is first designed and its transmission characteristic is analyzed. To increase the bandwidth of stop band, two SSG FSS layers are stacked with some spacing in‐between. It shows very wide stop band (over 255 MHz) covering both the uplink and downlink of PCS band and, furthermore, has good angular sensitivity. © 2008 Wiley Periodicals, Inc.
