In this article, a frequency selective surface (FSS) cell is proposed. The band stop frequency performance is compared between the two and four layer FSS structure with the proposed cells. The four‐layer structure has the same low frequency as the two‐layer structure, but the four‐layer structure has 3.6 GHz wider stop band in high frequency. Then, a reflector with the proposed EBG cells for ultrawideband antenna is developed. The performance for the reference antenna with and without the proposed reflector was compared, the average improvement of the front‐to‐back ratio of the UWB antenna with designed FSS reflector is 15 dB from 3.1 to 10.6 GHz and the peak even can get to 30 dB at 5 GHz. © 2013 Wiley Periodicals, Inc.
