A wideband and high‐gain electromagnetic band‐gap resonator antenna for X‐band operation is presented in this paper. A dual‐layer partially reflective surface with a wide frequency band from 8.3 to 11 GHz is proposed to enhance the 3‐dB gain bandwidth of a simple planar antenna. The measured results indicate that the proposed antenna possesses a relative 3‐dB gain bandwidth of about 33.33%, from 7.95 to 11.13 GHz, with a maximum gain of 13.57 dBi. Moreover, the measured impedance bandwidth is about 35.53%, from 7.8 to 11.17 GHz, which fairly covers the 3‐dB gain bandwidth. Hence, the proposed structure surpasses conventional techniques for widening the 3‐dB gain bandwidth. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:98–101, 2017
