摘　　要：提出一种小型化三频微带天线。通过采用开槽以及曲流技术.使天线工作在900MHz,1.8GHz以及2.4GHz 3个频段,同时减小了天线的尺寸。研究表明,倒三角的结构很容易使天线工作在多频,通过调整开槽的深度和宽度,可以改变天线的工作频率。曲流技术的使用使天线在满足增益要求的同时,大大降低了天线的尺寸,从而实现了天线的小型化。A new triple-frequency microstrip antenna,which operates at 900MHz,1.8GHz and 2.4GHz,using slot technology and meandering to decrease the size of the antenna is designed. The research shows that it is easy for the structure of the inverted triangle to achieve multiple frequencies, which are selected by adjusting the slot width and depth. As a result of meandering, the size of the antenna is reduced significantly and the miniaturized antenna is obtained, while the antenna's gain is still satisfactory.
