摘要 本文通过可重构天线的理论和应用前景,设计了基于双开口环的多频方向图可控电控扫描天线。以往在频率可重构天线中,某一个频率工作的时候,另一个可重构频率并不能同时工作。不同于之前所应用的理论和方法,本文并没有应用切换速度比较慢的机械转轴以及数目较多的复杂的移相器结构来实现方向图可重构特性。本文通过一种新的方式来实现在方向图可重构的情况下,能同时产生频率可重构特性。当天线要工作在某个特定频率的时候,要想同时以相同的方式工作在另一个不同的频带的时候,天线可以实现多种工作模式共存的性能,即新的可调模式并不影响之前的基本工作模式。 By analyzing the thoery and the application of configurable antennas, this paper raises a novel configurable antenna based on diode switch structure has been presented in this paper.Differs from the traditional antennas which either has a complex structure or possesses a small change in patten., without multi-feed or mechanical spindle, it can achieve configurable patten changed in 360 degree only by peripherals circuit, and realize multi-frequency switch.
