【摘要】：本文主要针对微带阵列天线技术进行研究,重点是基于阵列天线之间的无线功率传输效率优化理论的应用。优化过程中,待设计阵列天线作为发射天线,引入另一个天线作为测试天线,当发射天线与测试天线之间的无线传输效率达到最大值时,可以得到最优解。利用文中提出的方法,完成了对几款阵列天线的设计、仿真、制造和测试。从理论和实验的角度研究了如何优化阵列天线的设计。本文主要研究的工作内容： 1、根据阵列天线的优化理论设计了4款4×4单元的不同聚焦距离的微带聚焦阵列天线和1款6×6单元的聚焦天线,并通过实测和仿真的结果证明文中提出的方法的可行性,该方法实现了在近场区域没有旁瓣的聚焦效果。 2、通过改变接收天线的位置和距离,用文中介绍的优化设计方法对智能天线进行了研究,完成了4款阵列天线的仿真设计,并从中选取了2款天线进行了实物制作,测试结果达到了预期的效果。最后对全文的研究做了总结,并对未来研究方向做了展望。
[Abstract]:This paper focuses on the research of microstrip array antenna technology, focusing on the application of wireless power transmission efficiency optimization theory between array antennas. In the optimization process, the array antenna is designed as the transmitting antenna and the other antenna is introduced as the test antenna. When the wireless transmission efficiency between the transmitting antenna and the test antenna reaches the maximum, the optimal solution can be obtained. Using the proposed method, the design, simulation, fabrication and test of several array antennas are completed. How to optimize the design of array antenna is studied theoretically and experimentally. The main work of this paper is as follows: 1. According to the optimization theory of array antenna, four microstrip focusing array antennas with different focusing distances and one focusing antenna with 6 脳 6 elements with 4 脳 4 elements are designed. The feasibility of the proposed method is proved by the experimental and simulation results. The method realizes the focusing effect of no sidelobe in the near field region. 2. By changing the position and distance of the receiving antenna, The smart antenna is studied with the optimized design method introduced in this paper. The simulation design of four array antennas is completed, and two antennas are selected to make the object. The test results reach the desired results. Finally, the paper summarizes the research and prospects the future research direction.
