随着技术的发展和社会的进步，无线通信已经与每个人的生活密切联系在一起，且实现不同地点的高质量无线通信一直以来是无线通信研究者所面对的问题。目前，电子设备的天线的位置通常是固定的，因而天线的辐射方向图是固定的，也即天线的主波束的方向是固定的，而不能根据电子设备与信号源的相对位置变化进行调整。以移动终端为例，许多移动终端内GNSS(Global Navigation Satellite System，全球导航卫星系统)天线的辐射方向图，即主波束，往往不是朝着的天空方向，相反地，往往是朝着移动终端底部，故信号的接收效果与性能往往较差，无法满足大屏移动终端不同持握场景下无线通信性能的需求。With the development of technology and the progress of society, wireless communication has been closely related to everyone's life, and realizing high-quality wireless communication in different locations has always been a problem faced by wireless communication researchers. At present, the position of the antenna of the electronic device is usually fixed, so the radiation pattern of the antenna is fixed, that is, the direction of the main beam of the antenna is fixed, and cannot be adjusted according to the relative position change of the electronic device and the signal source. Taking the mobile terminal as an example, the radiation pattern of the GNSS (Global Navigation Satellite System, Global Navigation Satellite System) antenna in many mobile terminals, that is, the main beam, is often not facing the direction of the sky, on the contrary, it is often towards the bottom of the mobile terminal , so the signal receiving effect and performance are often poor, which cannot meet the requirements of wireless communication performance in different holding scenarios of large-screen mobile terminals.
在现有技术中，针对天线主波束方向较为固定的问题，目前尚未提出有效的解决方案。In the prior art, no effective solution has been proposed for the problem that the main beam direction of the antenna is relatively fixed.
