随着经济和科技的发展，天线并不是一味的强调低成本，有些领域可能更需要天线在成本适中且整体能耗较低情况下提供高质量的电波覆盖。为此要求天线能够根据有无目标、目标多少及位置分布等情况进行波束汇聚和方向调控，使有限的能量始终相对集中到需要的方向上，从而实现需要覆盖则能覆盖、覆盖质量好、整体能耗低的功能。然而现有天线不具有自我感知和调控的能力，难以做到这一点。本项目拟研究的天线是自身可以通过超声、光、电等多物理量获取手段，感知环境目标信息并自动将波束汇聚到所需地方的智能天线；将以室内和高铁隧道为应用背景，研究适用于一定范围的基于多物理量信息获取的智能天线。本项目将充分利用当前电子科技的成果，将小型、微型功能多样化的传感器和数据处理芯片与天线融合和集成设计，希望使天线自身变成像人眼一样，始终将波束汇聚到所关注的目标上，从而建立起动态灵活的高质量信息传输通道，使总能耗保持较低，降低电磁环境污染。

With development of economy and science, the design of antenna is not only emphasized on the low cost, probably, in some applications, it is required to have a reasonable cost, but plays important role in providing a high quality radio wave coverage with a total low energy consuming. So, it is demanded that the beams of antennas can be changed flexibly according to the distribution of objects, and focus the limited energy to where it is desired, so that the antennas can provide radio wave coverage with good quality, low energy consumption, and have functions of switching on/off the coverage according to the demand. However, the available antennas cannot provide such functions, because they do not have the sensing and controlling ability themselves. This project plans to do some study on the antennas who themselves have the sensing ability and can automatically focus their beam to the places desired. This functions will be realized by using and dealing with the multi-physical information collected by the supersonic, laser, and electronic techniques. This project will take the room and tunnel as application environments, and design the smart antennas for such certain areas based on the collection of multi-physical information. It will make use of the achievements of electronic science and technology, and integrate the small size, multi-function sensors and DSP chips into the antenna design. So the antennas can have function like human eyes, which can always focus their beam onto the objects that we care. Therefore, dynamic information tunnels can be established with the data transmitted in them stably. But the total energy consumption and the electromagnetic pollution will be reduced.
