In this article, a novel polarization‐insensitive and angularly stable miniaturized frequency selective surface (FSS) has been presented. The proposed structure has a single bandpass operation centred at 1.42 GHz, which is printed on an ultra‐thin (0.00127λ 0 ) dielectric substrate. Compared with earlier reported structures, the designed FSS demonstrates a better miniaturization performance having unit cell dimension of 0.0378λ 0 × 0.0378λ 0 , where λ 0 refers to free space wavelength corresponding to resonant frequency. Furthermore, an equivalent circuit model has been derived whose circuit simulation matches well with the full‐wave analysis. Finally, a prototype of proposed FSS is fabricated and the measured responses are in good agreement with the simulated results under normal as well as oblique incidence. © 2016 Wiley Periodicals, Inc.
