Description

天线系统及移动终端 技术领域
本发明涉及天线技术领域，尤其涉及一种天线系统及移动终端。
 背景技术
5G作为全球业界的研发焦点，发展5G技术制定5G标准已经成为业界共识。国际电信联盟ITU在2015年6月召开的ITU-RWP5D第22次会议上明确了5G的三个主要应用场景：增强型移动宽带、大规模机器通信、高可靠低延时通信。这3个应用场景分别对应着不同的关键指标，其中增强型移动带宽场景下用户峰值速度为20Gbps，最低用户体验速率为100Mbps。目前3GPP正在对5G技术进行标准化工作，第一个5G非独立组网(NSA)国际标准于2017年12月正式完成并冻结，并计划在2018年6月完成5G独立组网标准。3GPP会议期间诸多关键技术和系统架构等研究工作得到迅速聚焦，其中包含毫米波技术。毫米波独有的高载频、大带宽特性是实现5G超高数据传输速率的主要手段。
毫米波频段丰富的带宽资源为高速传输速率提供了保障，但是由于该频段电磁波剧烈的空间损耗，利用毫米波频段的无线通信系统需要采用相控阵的架构。通过移相器使得各个阵元的相位按一定规律分布，从而形成高增益波束，并且通过相移的改变使得波束在一定空间范围内扫描。
目前3GPP规定了毫米波n257band带宽范围为26.5GHz~29.5GHz，在高介电常数壳体下（例如3D玻璃，陶瓷壳体）实现3GHz带宽的阻抗匹配存在较大的天线设计挑战，传统的方式或采用叠层贴片,缝隙耦合馈电或者增加介质基板的厚度拓展天线带宽。
3D玻璃或者陶瓷等高介电常数壳体是未来全面屏手机结构设计中的主流方案，能提供更好的保护、美观度、热扩散，色彩度以及用户体验。然而较高的介电常数会严重影响毫米波天线的辐射性能，降低天线阵列增益等。
