A compact multiband antenna is presented by using a metal–insulator–metal (MIM) ring resonator in its ground plane. Two arrays of corrugated MIM are served as ring resonator and surround the radiating patch. The localised surface plasmons of the resonator are excited by the patch to show multi‐band operation of antenna. Design procedure of ring resonators and its impact on the impedance matching in multi‐band operation is studied and the results are validated by experimental analysis of fabricated structure. The presented CPW‐fed antenna operates at five bands, WLAN in 2.4‐GHz (2.4–2.484 GHz), 5.2‐GHz (5.15–5.35 GHz), C‐Band in 6.5‐GHz (6–7 GHz) and X‐Band in 9‐GHz (8.5–10 GHz), 9.8 GHz (9.7–9.9 GHz).
