Abstract: A dual-antenna building block with high isolation is presented for metal-rimmed fifth-generation (5G) smartphones. A coupled-fed loop antenna and a coupledfed slot antenna based on a simple T-slot etched on the ground plane are meticulously designed to form a compact building block. Notably, although the coupledfed
loop antenna and the coupled-fed slot antenna share the same aperture, a desirable isolation of >30 dB is exhibited. Afterward, an 8×8 multiple-input multipleoutput (MIMO) system is achieved by integrating four such dual-antenna building blocks. The measured mutual coupling and envelope correlation coefficients (ECCs) of the presented 8×8 MIMO system are <−18.5 dB and <0.02, respectively.
