A design of partially reflective surface (PRS) for Fabry–Perot resonator antenna to simultaneously achieve axial ratio bandwidth and broadside‐gain enhancement is demonstrated. A simple wideband stacked patch antenna that operates at X‐band (8–12 GHz) is used as a radiation source to demonstrate the performance of this design. The proposed antenna has a PRS array comprising of 11 × 11 unit cells tapered which features 16.9 dBi maximum broadside gain and 12.7% common bandwidth from 8.8 to 10.0 GHz.
