加载技术在天线小型化设计中的研究

Research on Loading Technology for Miniature and Broadband Antenna Design

研究学习了加载技术及其与其他小型化、宽带化技术的组合应用,并介绍了加载的优化设计,通过最优化分析寻求加载的最优位置、加载形式、元件值,从而设计满足指标要求的宽带小型化天线。由于天线的方向系数、效率、带宽和体积尺寸等构成矛盾的关系,如何协调和折衷上述关系获得最佳天线结构,成为宽带小型化天线设计的核心问题。研究表明,将加载和其他技术的整合应用是未来天线设计的发展趋势。

The paper studies antenna loaded and combines with other miniature and broadband technology,and introduces optimization of loading design. It can be obtained the best load location, form and element numerical value by optimization. Thus a design satisfies the target request the wide band miniaturization antenna. As a result of the antenna directive coefficient, the efficiency, the band width and the volume size and so on are the constitution contradictory relations, how coordinated and the compromised above relations obtain the best antenna structure, becomes core question which the wide band miniaturization antenna designs. The research indicates load combines with other technology will be the trend of antenna design.
