Abstract: A 3D printed metallized Fabry–Perot cavity antenna centred at 5.8 GHz is presented in this letter. A non-uniform grid superstrate and a choke groove are employed in the Fabry–Perot cavity antenna to improve the input bandwidth and decrease the side lobes. By using the non-uniform superstrate, the |S11| ← 10 dB bandwidth is enhanced to approximately 6.4% (from 5.65 to 6.02 GHz). The side lobes decrease to −14.03 and −21.62 dB on E and H planes by the choke groove. The designed antenna is fabricated by using a stereolithography-based 3D printing technique for verification, whose weight is only 13% of the one fabricated with copper. The measured result agrees well with the simulated one.
