摘要：
An 18-element multiband massive MIMO antenna system is proposed for 5G-enabled smartphones. The radiating units are engineered to operate within the frequency ranges of 3.4-3.6 (LTE Band 42), 3.6-3.8 (LTE Band 43), and 5.15-5.925 GHz (LTE Band 46). A simple open-ended U-shaped slot radiator with metallic side frames is used. The metallic side frames improve the robustness of the handset. Open-ended slots integrated into the side frames help reduce mutual coupling between the radiating elements. Simulated and measurements show excellent envelope correlation coefficients (< 0.07) and total efficiency ( >87%) across the full operational bandwidth. The massive MIMO capabilities of the proposed design are evaluated through ergodic channel capacity analysis (>96 bps/Hz) using the Kronecker channel model. Furthermore, the influence of real-world factors such as human hand grip, LCD, and battery components is thoroughly examined.
