摘要：
The design of a wideband millimeter wave twoport multiple-input-multiple-output (MIMO) array antenna appropriate for 5G applications is presented in this work. The intended antenna wider impedance bandwidth (IBW), circular polarization radiation, and higher gain response are obtained due to the loading of a staircase-shaped circular polarization converter-based metasurface (MS). Using this concept, a twoport MIMO antenna is designed. The intended MIMO antenna provides a wider IBW of 34.1% (23.61 GHz to 33.3 GHz), a higher gain of 11 dBi at 26.1 GHz, and isolation is more than 30 dB due to the placement of modified mushroom-based MS. Furthermore, the antenna provides polarization diversity mechanism, with antenna-1 provides right-handed circular polarization (RHCP) and antenna-2 provides left-handed circular polarization (LHCP) radiation.
