摘要
En 中文
In this study, we propose a multiple-input/multiple-output (MIMO) antenna array for fifth-generation (5G) mobile-phone applications. Its configuration is composed of eight planar loop antenna elements located at different edges of the mobile-phone mainboard with 75 x 150 x 0.8 mm(3) FR-4 dielectric. In order to easily integrate with phone circuits, the ground-plane and antenna resonators have been etched on the same side of the substrate. By addling modified arrow-shaped strips among the adjacent loop antennas, the operation bandwidth and isolation level of the closely spaced radiators have been improved. The presented MIMO antenna is designed to cover the spectrum of commercial sub 6 GHz 5G network with the bandwidth of 3.2-4 GHz. Due to the compact size and placements of the loop radiators, the presented MIMO antenna array occupies a small part of the board. In addition, the proposed array provides not only full radiation coverage covering different sides of the PCB but also the diversity function to support both vertical and horizontal polarization. The MIMO performance and radiation behavior of the proposed antenna design in the presence of the user-hand/user-head phantoms are also discussed. Moreover, a new and compact phased array millimeter-wave (MM-Wave) antenna with broad bandwidth and end-fire radiation is introduced to be easily integrated into the smartphone antenna system.
