A two‐element super‐wideband (SWB) MIMO antenna is proposed in this study. A step impedance microstrip feed line structure is introduced to achieve an SWB impedance bandwidth of 185%. This antenna is designed to be circularly polarised at 1.575 GHz (L 1 ‐band) and 26.0 GHz (K‐band) by using closed ring resonator on the radiating patch. The EBG structures are used to improve FBR in lower (1.5–5 GHz) and higher bands (25–35 GHz). The proposed antenna is designed with compact size 55.6 × 50.5 × 1.6 mm 3 on FR‐4 substrate including exotic diversity performance. This MIMO antenna is suitable for defence and handheld devices covering GPS/DCS/PCS/UMTS/Wi‐BRO/ISM/IRNSS/LTE (M/HB)/BLUETOOTH/IoT/WiMAX/X/Ku/K/Ka‐band and it is also suitable for 5G (sub‐6 GHz/mm) applications with channel capacity of 11.34 bps/Hz. Simulated results of MIMO antenna like radiated power‐based ECC and diversity parameters are also verified experimentally, which are in the acceptable range. Finally, this antenna is tested in a realistic environment for SAR application.
