Abstract

Abstract: In this paper, a miniaturized integrated frequency selective surface (FSS) is proposed. It is composed of two parts: the band‐stop FSS and band‐pass FSS. Through introducing six capacitors between the hexagonal gap of band‐pass FSS, a miniaturized dimension of 0.07 λ 0 × 0.07 λ 0 × 0.036 λ 0 ( λ 0 is the wavelength of the transmission band in free space) is achieved. As a result, the presented FSS effectively avoids grating lobes and remains stable when the incident angle changes. In addition, by coupling between the band‐stop and band‐pass FSSs, the ultra‐wide‐band absorption is realized. The results show that the insertion loss at 2.2 GHz is only 0.6 dB and the bandwidth with the absorptivity larger than 90% is 12.6 GHz (6.8–19.4 GHz). Besides, the integrated FSS has good polarization and angular stability.
