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 USE OF AUTHENTIC FILMS WITH SUBTITLES IN THE PROCESS OF LEARNING NEW VOCABULARY IN HIGHER EDUCATION SECTOR (AS BASED ON THE ENGLISH LANGUAGE MATERIAL) 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 Independent Research as a Resident Physician: Novel Methods for Data Collection, Teaching, and Collaboration During Graduate Medical Training −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.
