摘　　要：漏波天线是一类具有广大应用前景的导波天线,与传统天线相比具有明显的优势,可为各种无线通信和雷达应用提供波束控制功能。本文提出一种使用容性负载实现方向图动态辐射模式控制的漏波天线设计及波束控制方法。波束控制方法作为研究的主要重点,即在天线结构的特定位置引入电容元件来调制导波的有效折射率,通过改变波束的辐射角度来实现波束的控制。此外,研究还通过改变容性负载的参数分析了不同参数的容性负载对漏波天线辐射特性的影响。该技术具有结构简单、低成本、易小型化等特点,可以集成到各种无线通信系统和雷达阵列中。Leaky wave antennas are a class of guided wave antennas with broad application pros⁃pects.Compared with traditional antennas,they have significant advantages and can provide beam control functions for various wireless communication and radar applications.This paper proposes a design and beam control method for leaky wave antennas using capacitive loads to achieve dynamic radiation pattern control.The beam control method is the main focus of the research,which intro⁃duces capacitive elements at specific locations of the antenna structure to modulate the effective re⁃fractive index of the guided wave,and achieves beam control by changing the radiation angle of the beam.In addition,the study also analyzes the influence of different parameters of the capacitive load on the radiation characteristics of the leaky wave antenna by changing the parameters of the capaci⁃tive load.This technology has the characteristics of simple structure,low cost,and easy miniaturiza⁃tion,and can be integrated into various wireless communication systems and radar arrays..
