Abstract

This study presents a lightweight, compact Metasurface-inspired UWB-optimized MIMO antenna featuring high isolation and substantial gain. The MIMO antenna design incorporates two identical patches arranged in parallel to boost overall performance. To enhance impedance matching, a trapezoidal defected ground with stepped features is employed. The antenna's feed, designed in a tapered shape, contributes to enhanced impedance matching. A metasurface isolation system is implemented, utilizing a hexagonal-shaped unit cell absorber, which is subsequently integrated into the middle of the defected ground. Metasurface achieves significant isolation, up to 25 dB. The antenna abilities to provide a wide operating bandwidth of 1.96 GHz to 13 GHz, suitable for UWB utilization, with a peak gain of 7.9 dBi at 7 GHz. A comparison with prior literature demonstrates size optimization and enhanced isolation through the novel metasurface absorber. The efficiency of the proposed antenna stands at 95.5%. Resonating at triple frequencies 5.2 GHz, 7.5 GHz, and 12.37 GHz, this MIMO metasurface antenna is well-suited for applications such as WPAN and WBAN.
