- 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.
