A Study of Mutual Coupling Suppression between Two Closely Spaced Planar Monopole Antenna Elements for 5G New Radio Massive MIMO System Applications

Abstrakt

5G NR (new radio) introduces the concept of massive MIMO (multiple-input-multiple-output) technology, in which a larger number of antenna arrays are installed on the transceiver. Due to the increased number of antenna elements allocated close to each other (approximately at half-wavelength distance), mutual coupling becomes a serious problem leading to performance degradation of the MIMO communication system. In this communication, two different config-urations of closely-spaced antenna array elements are studied. In order to reduce the mutual coupling, a combination of a metamaterial-based frequency selective surface (FSS), a metallic strip, and a slot element in the ground plane, is examined. It has been found that the proposed technique significantly suppresses mutual coupling from –12dB to –25dB. Both designs are fab-ricated and experimentally validated. The simulation results are in good agreement with the measurements. The proposed mutual coupling reduction technique may be suitable for massive MIMO systems in the fifth-generation (5G) new radio applications.
