Abstract

The design presents a revolutionary approach to effective antenna solutions in 5G devices, including a ground-breaking decoupling method for a dual-band, tightly organized MIMO antenna pair. By integrating a bent loop and Circle Shape dual-band architecture, it addresses the issues of compactness, bandwidth, and isolation in 2x2 MIMO systems. It supports a wide range of 5G frequency bands by using several orthogonal modes for dual-band operations. Geometrical parameters that have been optimized achieve great isolation, which reduces mutual coupling. The tiny size, dual-band capabilities, and high isolation improve smartphone performance. Validation through simulation and testing confirms effectiveness under a variety of scenarios while meeting 5G criteria. The operational frequencies of the planar antenna include 2GHz, 4.8GHz, 5.8GHz, and 6.2GHz, which are -16 dB, -20.2dB, -15.5dB, and -20.2dB, respectively.
