论文摘要
作为媒体设备，智能手机应在包装良好的设备中提供大型屏幕和快速的数据速率。基于毫米波的新兴5G技术需要有效地辐射天线，这些天线集成到其身体（尤其是玻璃屏幕）的设备中，在天线频带中表现为波导。使用后表面的概念，这项工作提出了位于智能手机玻璃屏幕下方的紧凑型超面，可减少地表波的激发和传播，并显着提高集成到移动终端的毫米波天线的辐射模式和效率。
The smartphone, as a media device, should offer a large-size screen and fast data rates in a well-packed device. Emergent 5G technologies based on millimeter waves need efficiently radiating antennas integrated into devices whose bodies (especially glass screens) behave as waveguides in the antenna frequency bands. Using the concept of retroreflective surfaces, this work proposes a compact metasurface located below the smartphone glass screen which reduces surface-wave excitation and propagation, and significantly improves the radiation pattern and efficiency of millimeter-wave antennas integrated into mobile terminals.
