摘要
可重构天线作为一种新型的天线,与传统天线相比具有尺寸小、重量轻、利于实现分集等优点和广阔的发展前景。回顾了可重构天线的发展历程,总结了近年来国内外关于可重构天线的最新研究成果,并从可重构天线的功能、使用的关键器件、设计方法与电路特点等方面对其研究现状进行了深入分析。从多个角度给出了可重构天线的分类与总结,并就可重构天线的设计方法与电路特点进行详细论述和举例说明。最后对可重构天线的发展趋势进行了展望。
As a anew concept antennas, reconfigurable antennas have more advantages and better prospect compared with conventional antennas. They are lighter in weight, smaller in dimension and beneficial to the diversity. In this paper, the development background of reconfigurable antennas is presented. And the latest researches are analyzed and summarized to present the function, implementation, circuit design features of reconfigurable antennas. The implementation of reconfigutable antennas and the circuit design features are specifically illustrated and exemplified, while the classifications and summaries are presented in various respects. The trend of reconfigurable antennas＇ development is given at the end of the paper.
