Abstract

We present an angular stable dual-band frequency selective surface (FSS) in this paper. By placing anchor-shaped elements with different structural parameters along x-axis alternately within hexagonal wire grid, the proposed FSS can provide two closely spaced passbands. And the resonant frequency ratios are only 1.16 and 1.19 for TE and TM polarizations, respectively. In addition, the proposed FSS has stable frequency response under oblique incidence, and resonant frequency deviation is below 0.5% within 60° incident angle. An FSS prototype is fabricated and measured for further verification, and good agreements between the simulated and measured results can be observed.
