“…Due to the expectation of high data rates and high reliability, the multiple input multiple output (MIMO) technology is used in mobile devices with limited space in the future 5G communication systems . Many MIMO antenna designs for 5G wireless application with good radiation characteristics are proposed . Nevertheless, the simultaneous requirements for small space occupancy, multi‐band coverage, high isolation among the radiators, and high radiation performance in mobile communication have brought great challenges to the MIMO antenna design.…”

In Reference , a meander‐line resonator is placed between two radiated elements to reduce the coupling, but its overall structure is too complicated and occupies much space . Although various methods for matching and decoupling are used in MIMO antennas, these antennas either have complex structures and occupy large spaces or are not easy to be integrated and fabricated.…”

“…1 Many MIMO antenna designs for 5G wireless application with good radiation characteristics are proposed. [2][3][4][5][6] Nevertheless, the simultaneous requirements for small space occupancy, multi-band coverage, high isolation among the radiators, and high radiation performance in mobile communication have brought great challenges to the MIMO antenna design. There are two challenges to be solved urgently: the full-band coverage and the high isolation for the MIMO antenna.…”

A novel compact planar dual‐band multiple input multiple output (MIMO) antenna with four radiating elements for 5G mobile communication is proposed. Each radiating element has a planar folded monopole, which is surrounded by L‐shaped meta‐rim extended ground stubs. The compact folded arms act as the main radiating elements, while combined with the L‐shaped meta‐rim stubs, the proposed antenna forms multiple resonances so as to achieve dual‐band coverage. The simulated and measured results show that the proposed antenna has two wide bands of −6 dB return loss, consisting of 1.6 to 3.6 and 4.1 to 6.1 GHz, respectively. Without any additional isolation structure between the elements, the isolation for the proposed 2 × 2 MIMO antenna in both desired bands can be achieved better than 12 dB. The measured results show that the proposed MIMO antenna with good performance, that is, stable radiation patterns, high efficiencies, low specific absorption ratio (SAR) to human tissues, is suitable for WLAN/LTE, 4G and future 5G mobile phone applications.
