Abstract

ABSTRACT Liquid crystal technology has a long well-established history of applications in visible light, primarily in the display industry. In contrast, applications at lower frequencies (microwave through infrared) are less common. In this paper, we examine non-display applications and review the use of liquid crystal materials for tunable signal processing devices operating at microwave and millimeter wave frequencies. These devices include tunable phase shifters, filters (bandpass and bandstop), antennas and antenna arrays, resonators, and frequency selective surfaces. We also give a short review of the typical characteristics of liquid crystals in these frequency ranges.

液晶信号处理应用于微波和毫米波频率范围

液晶技术在可见光领域有着悠久的应用历史，主要是在显示行业。相比之下，在较低频率(微波到红外)的应用不太常见。在本文中，我们研究了非显示应用，并回顾了液晶材料在微波和毫米波频率下可调谐信号处理器件中的应用。这些器件包括可调谐移相器、滤波器(带通和带阻)、天线和天线阵列、谐振器和频率选择表面。我们还简要回顾了液晶在这些频率范围内的典型特性。
