摘要：
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 x 50.5 x 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.
