Abstract
Abstract In this article, a wideband self-isolated multiple-input multiple-output (MIMO) antenna element based on multiple adjacent modes coupling current cancellation is proposed for 5G mobile terminal. The wideband self-isolated technology based on multiple adjacent mode coupling current cancellation are demonstrated. With the combination of five adjacent loop modes, the −6 dB bandwidth of the proposed self-isolated element can cover 3.3–3.8 GHz and 4.4–5.0 GHz. Finally, an 8 × 8 MIMO array is constructed by arranging eight proposed wideband self-isolated antenna elements on the two long sides of the mobile terminal. Simulated and measured results show that the isolation of 8 × 8 MIMO array exceeds 15 dB without any decoupling structures in the operating frequency band. The proposed antenna elements are simply arranged to obtain a wideband high isolation MIMO array, and it is a good choice for 5G mobile terminal.
期刊介绍：
Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal.
Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies.
RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
