论文摘要
振幅调节(AM)泄漏波天线(LWA)是经典通信理论振幅调制技术的概念,是一种有前途的结构,可以使行动波转换为辐射波。在本文中,我们基于经典全息理论提供了不同的观点,以深入了解AM LWA和设计小说LWA的物理机制。类似于经典的光学Gabor全息图,我们证明了仅需要传导波的幅度变化来记录对象波的振幅和相位信息。还展示了全息理论与先前解释AM LWA操作机制的空间光谱方法之间的一致性。出于验证目的,设计了两个基于底物集成插图介电性波导(IDW)的新型毫米波(MMW)全息AM LWA。第一个是用于远场高增益应用程序,而第二个是用于近场聚焦(NFF)应用程序。模拟和测量结果都证明了AM全息理论在LWAS分析和设计中的有效性。
Amplitude-modulated (AM) leaky-wave antenna (LWA), a concept following amplitude modulation technique from classical communications theory, is a promising structure that enables transforming traveling wave into the radiating wave. In this paper, we provide a different perspective based on the classical holographic theory to gain insight into the physical mechanism of AM LWA and design novel LWAs. In analogy to the classical optical Gabor hologram, we demonstrate that only the amplitude variation of the traveling wave is needed to record both the amplitude and phase information of the object wave. The consistency between the holography theory and previous spatial spectrum approach for explaining AM LWA operating mechanism is also demonstrated. For validation purpose, two novel millimeter-wave (mmW) holographic AM LWAs based on the substrate integrated inset dielectric waveguide (IDW) are designed. The first one is for far-field high-gain applications while the second is for near-field focusing (NFF) applications. Both simulated and measured results demonstrate the effectiveness of the AM holography theory for AM LWAs analysis and design.
