Abstract
Conference Title: 2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting Conference Start Date: 2018, July 8 Conference End Date: 2018, July 13 Conference Location: Boston, MA, USA This paper presents the design of a novel wideband bandpass frequency selective surface (FSS), which is comprised of sandwiched arrays of cascaded back-to-back patch resonators with a C-type slotted ground in-between. Three transmission poles are generated to realize the desired wideband frequency responses, with a 3-dB fractional bandwidth of 85% and an insertion loss of 0.27 dB at the center frequency of the passband when the incidence is normal. The out-of-band rejection bandwidth is shown to range from 14.5 GHz to 22.8GHz for the presented design, though it is scalable.
